Corrtef® Fluoropolymer Tubing
Corrtef Fluoropolymer Corrugated Tubing is heat sealable, and the cuffs (straight ends) are made to accept standard barbed fittings The end may be flared or expanded to permit shrink-tight connections. For optimal cleaning of Corrtef, the tube should be stretched to its maximum length and held vertically (direction of flow: down). It may not be possible to remove all traces of particulate. Vacuum Service at 72°F: 29.9 in./Hg. Bend Diameter at 72°F: 1/2 of tubing ID. Optimal flow is achieved and turbulence minimized by passing fluids through Corrtef in the direction of the corrugation angles (as illustrated). Overbraiding with Kevlar, available for sizes up to 7/8” ID, will permit a minimum increase of six times the listed pressures.
- Made from FEP fluoropolymer tubing
- Corrugations allow a nearly zero bend radius
- Can be extended or compressed without affecting I.D.
- Made without plasticizers which can leach
- Made from FDA compliant materials
- Has all the chemical and electrical properties of straight-walled FEP tubing
- May be overbraided with Kevlar® for higher pressures^

NOTE: Values listed are typical for the material used in manufacture, except where noted, and are meant only as a guide to aid in design. Field testing should be performed to find the actual values for your application.
†Temperatures are for standard extruded (non-convoluted) tubing.
Cut Pieces – When tubing comes in, for example, 100 foot coils, and you need it in 10’ sections, tubing can be cut. Request a quote.
Size – Tubing is stocked in common I.D. and O.D. sizes, but this product can be custom extruded in other sizes. Let’s talk about what you need. Minimum quantities apply.
Color – Have your tubing colored to match equipment, company colors, or identify line (hot or cold, indoor or outdoor, chemicals, etc..).
Opaque and transparent colors may be accommodated. Minimum quantities apply.
All custom products are subject to minimum order quantities and lead times. For other custom options, please contact us.

Specify ‘E’ dimension at order time. Maximum overall available length: 12 ft. (including cuffs). The minimum overall length for Corrtef with a cuff at each end is 6”; shorter available for one cuff.
Workable I.D. length of the cuff (straight ends). All lengths supplied with ‘B’ dimension cuffs.
All pressures are calculated and not based on actual testing.
B is the critical dimension for fittings application.
