SILICONE HOSE TECHNICALINFORMATION SALES BULLETIN

..................................................................................................... -_.- _- .

ABOUT SILICONE HOSENorthern Silicone Hoses are manufactured using only certified and graded Silicone, Polyester, Nomex, Ammidand Stainless Steel materials. The finished goods ore monufactured and tested to meet and exceedASTM** and SAE* testing methods ond results.

*SAE= Society of automotive engineers.**ASTM= American Standard testing method.

We manufacture silicone hoses for a variety of tasks. Some manage coolant flow, somecold air intake and some hot compressed air. All these hoses use different materialcombinations to meet the challenge required .

CHARGE AIR COOLER HOSEOur 500~ F (horge oir cooler hose operotes with compressed air temperatures mnging from-762 F to 5002 F. For these difficult conditions we use Nomex/Aromid reinforcement and silicone rubber gradeTSE 2267A which exceeds the requirements for high temp oil resistant silicone SAE designation of doss A.We use 4 layers of Nomex as a combination of Aramid/Nomex reinforcement to meet or exceed thetempemture and burst strength requirements of this type of chorge air cooler hose.

For certain types of chorge air cooler hose we add stainless steel reinforcing rings to avoid hose ballooning andprevent hose blow off.Northern silicone turbo charger hoses ore ovoiloble in both straight and shaped configurations.

For our liquid carrying silicone hose we use a O.5mm thick flouro-silicone hose liner to prevent hose erosionand substantially increase hose life. These hoses may be reinforced with 3 or more loyers of Polyester, Nomex,Fiberglass or combinations of these materiels to handle the coolant pressure, prevent fatigue, and increase hose life.

SILICONE HUMP HOSENorthern Silicone "HUMP HOSES" are designed for air or coolant flow in oreos subject tomisalignments, vibration or transition. These hoses ore designed to operate in environments of-127~ F to +3802 F and are manufactured with either 3 or 4 plies of heavy polyesterreinforcement. Northern Hump Hoses ore ideally suited for mining and construction

equipment, stationary engines, form equipment, passenger vehicles, H~t Rods, and otherindustrial applications.

NORTHERN SILICONE STICK RADIATOR HOSEManufactured to exceed SAE 20R4 specifications, Northern 3 layer, reinforcedsilicone stick radiator hose means high-tech construction andcut to length accuracy. Designed for difficult environments of-100Q F to +380Q F, these radiator hoses are engineered for todays high coolanttemperatures and high pressure cooling systems.
