Notes

CONTEF’s helical construction aids in self-cleaning when flushed with standard cleaning fluids.

 

The cuffs (straight ends) are made to accept standard barbed fittings. Hose assemblies made to your specifications are available.

 

PTFE’s color will vary naturally from lot to lot, but the quality and physical properties do not change.

 

FEP CONTEF for longer continuous lengths is available through custom order.

 

CONTEF Without Wire: Vacuum Service: 27 in.Hg at 72°F. The convolutions are molded into the tubing and will not cold flow into a straight wall under normal conditions.
