All items in the LF3800 range are SILICONE FREE

The working specification depends on the type and wall thickness of the tube, the type of fluid, fluid temperature, and ambient temperature.

technical specification

The LF3800 range provides the advantages of push-to-connect fittings – instant connection anddisconnection – for a wider range of industrial applications. All are stainless steel construction and provided with aFKM ”O“ ring, LF3800 offers excellent resistance toaggressive environments and fluids.

To suit most applications, models are available:- for inch O.D. tubing with NPT thread.- for metric tubing with BSP taper thread, BSP parallel

thread and metric or NPT threads

LF3800 conforms to the following norms:- ISO- CETOP- AFNOR

maximum 290 psi depending on tube (see section on Legris tubing)

working temperature

5° to 230°F depending on the type and size of the tube.
