• 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 - convoluted / spiral construction allows far greater flexibility than straight wall tubing
• Spiral construction also allows for easier cleaning
• Made from FDA-approved ingredients
• Available to Military Specification MIL-T-81914/1^ (without wire only)

**Values listed are typical and are meant only as a guide to aid in design. Field testing should be performed to find the actual values for the application.
^^ Temperatures are for standard extruded (non-convoluted) tubing.

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 also available -- contact us for details.

Overbraiding for higher pressure capabilities is available.

PTFE's color will vary naturally from lot to lot, however, 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: 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 AMS (Aerospace Material Specifications) is available without wire only and is not stocked - call for details.

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.
