Contef® Convoluted PTFE Tubing

Check up to five results to perform an action.


  • 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-sanctioned ingredients
  • Available to AMS-T-81914/1 (without wire only)
    (CONTEF with AMS (Aerospace Material Specifications) is available without wire only and is not stocked)
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 - up to 500 ft. - is available through custom order.

CONTEF Without Wire:

Vacuum Service: 29.9 in./Hg at 70ºF.
Convolutions are molded into the tubing and will not cold flow into a straight wall under normal conditions.

CONTEF With Wire:

Vacuum Service: 29.9 in./Hg at 70ºF.
For high vacuum applications, CONTEF can be produced with wire on the I.D.
