Selecting Part Numbers

There are 3 very handy tools available to you when trying to help a customer select a cable gland to suit their needs. There is a Selection Chart at the beginning of the Hawke catalogue which gives you a quick reference point to start at. In addition to the selection chart there is a Selector Guide that was created by HWP Marketing (reverse side is the Redapt Selector Guide) which focuses on the most common glands sold in Canada and the United States. In addition to these two printed tools there is a selector tool on the Hawke website that customers can access and use to select an appropriate cable gland – this requires them to get a User ID and password from Hawke.

Let’s look at how each of the tools works, then we’ll try a few examples!

At the front of the Hawke Cable Gland catalogue you will find a chart which aids users in quickly finding the cable gland they require for their application. In order to use this chart you need a few key pieces of information:

1)Application – indoor/outdoor?

2)Cable Type – this is a key part of the puzzle. You need to know if the cable is armoured, and if so what type of armour (the different types were covered earlier in this module). You will also need to know if the cable is effectively filled as that will determine whether or not a barrier style gland is required.

3)Sealing method and Ingress protection – how does the gland seal around the cable?- what type of water ingress protection is required, if any?

4)Material – what is the gland made from? Most applications can use Brass, highly corrosive environments will often require Stainless steel or brass glands with special plating. Important note – due to the presence of H2S in many areas, Alberta applications will normally not accept Brass (or any “yellow” metal). If the customer is calling from AB ask them if Brass is acceptable.

5)Certifications/Approvals required – does the customer require CSA/UL approved glands, or ATEX (European) approved glands? This is also where you’ll need to find out what Hazardous Location ratings the customer requires.

Once you have this information, you should be able to narrow your selection down. Here’s a suggestion. Put an asterisk (or other mark) beside each of the following in your selection chart – 501/421, 501/421, 501/453/RAC, 501/453/Universal, ICG653/Universal, 153, 710, 711/713, 753, and 755 0 as these glands are the ones typically sold in Canada!

Based on the information you have collected to this point, you should be able to select a suitable series of gland using the chart in the catalogue. Always select the one that best meets all the customer’s requirements. If there are a couple that are about equal, have the customer look at the catalogue pages on line at www.ehawke.com and let them select the gland they prefer.

Building a Part Number

Once you have narrowed the choice down to a specific gland series, flip to that page in the catalogue. The Selection Chart includes a colour code and page number (next to the image of the gland) to help you find it quickly. The pages are all laid out the same. At this point you are trying to determine the exact part number the customer requires. There is a “Cable Gland Selection Table “ at the top of each page. This table provides details on dimensions of the gland, as well as body sizes, entry options, and cable acceptance ranges (this is the range of cable sizes that the body size sill accept).

The customer will need to tell you the outer diameter (over the out jacket) of their cable and the entry size they want. For example they may say that their cable is 12mm in diameter, and they need an M20 entry. This information is needed in order to determine the remainder of your part number. As a rule of thumb, always try to pick a body size so that the diameter of the cable is in the middle of the cable acceptance range. There is a guide at the bottom of the page that shows how to assemble a part number. One note, HCLP uses slightly different part numbers than those shown in the catalogue. Instead of 1 ¼” NPT we use 125NPT. For the example above, if you were looking at the 501453Universal (page 13) the part number would be 501453UNIVOM20 – we selected the O body size because it has an Outer Sheath (over armour) range of 9.5 – 16.0mm (12 is right in the middle). If we were out of stock, we could offer the customer a 501453UNIVOSM20 as the 12mm cable diameter is still within the range of this body. If they had asked for a ½” NPT entry, the part number would have been 501453UNIVO050NPT.

Building a Part Number

Let’s try one!

Let’s try building a part number.

A customer calls looking for a cable gland for an application.

What is the application? The cable is being used on a ship.Is the cable armoured? NoWhat type of seal do you want? Just an outer jacket seal. (Sometimes the customer may not be able to answer this question in which case you may need to enlist some help.)What material would you like? Brass will be fine.What certifications/approvals do you need? The equipment is going overseas, so I need an ATEX gland.

Based on this info, we can narrow the selection down to either the 501/421 or 501/423. The 423 has 2 seals, so the best choice is the 421 as it will be the least expensive solution for the customers application.

At this point you would flip to page 11 of the Hawke catalogue.

Building a Part Number

Use the Cable Gland Selection Table to select the body size and entry

Build your part number

Now that you’ve gotten this far, it’s all downhill. The next information you need is the outer diameter of the cable’s jacket (outer coating) and the entry size the customer wants.

What is the outer jacket diameter of your cable? 12.5 mm (you may sometimes get this in inches . . . If you do, simply multiply by 25 as there are 25mm in 1 inch).

What size of entry do you need? M20

So, what would the part number be?

Series – 501421Body – customer’s OD is 12.5mm, so the best choice is an A body as the range is 11.0 to 14.3mmEntry – M20 – this is available in the A body according to the Selection table (see columns under “Entry Thread Size”heading)

Part Number – 501421AM20

Selector Guide

On the reverse side of the Redapt Selector Guide you will find the Hawke Cable Gland Selector Guide.

To use this tool you will need the same information you required in order to use the Selector Chart in the Hawke catalogue. The big difference is that this Selector Guide puts everything you need to select a gland, and build the part number, in 1 place! And it narrows your choices down for you by listing only the glands most often sold in Canada.

In the center of the guide is the main details which list the “series prefix” and provide details as to the ratings and cable types each gland is suitable for. What it does not provide is details as to the approvals – the 501/421, 501/453, and ICG are ATEX glands. All the 7 series glands are CSA/UL approved. To the right if this information there are 2 tables. The first provides a list of available body sizes, and what size entry is available for each body size. If the entry size is not shown beside the body size, you cannot get it. For example, you will not see a ¾” NPT entry for an O body because it is not available. Below tat table is another table which converts NPT entry sizes and gives you the part number logic for each size. For example the part logic for a ¾” NPT entry is “075NPT”. On the bottom of the page is another table. Across the top it lists all the glands listed on this guide. Down the left side is all the body sizes. In the center of the table you will find the outer sheath (over armour) diameter range for each gland, and for each body size.

Selector Guide

To build a part number using this tool, first select the gland from the information acquired from the customer in regards to the type of cable, the application, and the certifications/approvals required. Once you have the series selected, use the table at the bottom of the page to determine the body size – remember that ideally we want the customer’s cable diameter to fall near the middle of the acceptance range in this table. Once you have the body size add the body size reference number to the series prefix, and double check that the customer’s desired entry is available in this body size – if not we could always supply a reducer/adapter to allow a smaller gland to be installed if the entry is already in the enclosure or equipment. Last, add the entry size suffix to the part number.

Let’s try an example.

Selector Guide

A customer calls looking for a Class I, Div 2 cable gland for a non-armoured cable. He requires that the gland be CSA/UL approved. The outer sheath (over armour) diameter is 0.55 inches and the customer needs a ¾” NPT entry.

Based on the fact that they want Class I, Div 2 approvals and have a non-armoured cable we know that they need a 710 series gland. (ATEX approved glands will not use Class/Division references in their approvals). Looking at the body size table at the bottom of the page, the O body is our best choice as the 0.55” diameter is in the middle of the O body range (0.37 – 0.63) HOWEVER in looking at the Entry Size table we see that the O body is not available with a ¾”NPT entry. We have 2 choices. The logical choice is to recommend the A body gland as it is available in ¾” NPT and will accept the customer’s cable. The other option would be to offer them the O body with ½” NPT entry, and a ¾” NPT to ½” NPT reducer. So what will the part number be for the A body gland?

Online Selector Tool

In order to use the online selector tool, customers must register with Hawke via their website. Registered users will be given a User ID and password. Once they log in, they will see the screen shown above. Selecting “Cable Gland Selection Application” will open a new window containing the selection tool. This tool guides uses step by step, asking them to provide all the information required to select an appropriate cable gland. When all the information has been provided, the tool will select an appropriate gland and display the part number. Keep in mind that the part number will not match Hubbell Canada’s Part logic for NPT entries, and will have to be adjusted in order to check price and availability.

Online Selector Tool

Once the user logs in, they will be met by the screen shown above. This screen allows the user to “Start a New Project”, “Open a Saved Project”, or “Give Feedback”. Starting a new project will take you to the next screen whichsimply asks for a Project Reference. Every Project is stored and tracked by Hawke UK. Each project created also generates a Sales Lead which is forwarded to the local Rep or Agent for them to follow up on. Once a Project Reference has been entered, the user clicks OK and the system checks to ensure that no previously saved projects exist under the same reference, and then proceeds to the next screen.

Online Selector Tool

Once the project name has been entered and confirmed, the user will see this screen – which asks them to select the approvals required for the application from the list provided. Once a selection is made, the user is taken to the next screen which asks them to select their cable type from a pre-determined list.

Online Selector Tool

Once the customer has chosen their cable type from the list provided, they will move to the next screen which asks them to provide details on the cable diameter. The look of this screen will vary slightly depending on the cable type selected as different types of cable require different information to be supplied. The next step will ask the customer to choose a sealing method based on their application.

Online Selector Tool

Once all the cable information has been provided, the software will ask the user for details on the construction of the gland – specifically the type of material it is to be made from, and the plating – if any is required. It also asks the user to select between Metric or NPT threads.

Once this information has been provided, the selector software will take the user to the final screen, which provides the final part number as well as the option to select accessories like locknuts, earth tags, and sealing washers.
