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.

'E' dimension to be specified at time of order. All lengths will be supplied with 'B' dimension cuffs. The minimum overall length for Contef™ with a cuff at each end is 6"; shorter overall lengths are possible when only one cuff is needed.

All pressures are calculated and not based on actual testing.
