Contef™ Convoluted PTFE
- Translucent PTFE tubing offers excellent chemical and electrical properties
- Available from stock with or without a stainless steel wire encircling the O.D.
- Wire coil provides increased pressure capability and aids in electrical grounding
- Easily flexed – spiral construction allows far greater flexibility than straight wall tubing
- Spiral construction also allows for easier cleaning
- Made from FDA compliant materials

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.
CONTEF With Wire: Vacuum Service: 27 in./Hg at 72°F. For higher vacuum applications, CONTEF can be produced with wire on the I.D. — call for details.
