REQUEST A QUOTE

Features

  • Made from FEP fluoropolymer tubing
  • Corrugations allow a nearly zero bend radius – easily flexed
  • Can be extended or compressed without affecting the tube’s I.D.
  • Made without plasticizers which can leach into critical streams
  • 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^

**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.

Notes

Vacuum Service at 72°F: 29.9 in./Hg.

 

Bend Diameter at 72°F: 1/2 of tubing I.D.

 

Optimal flow is achieved and turbulence minimized by passing fluids through CORRTEF in the direction of the corrugation angles (as noted).

 

CORRTEF 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.

CORRTEF is manufactured in an industrial atmosphere and should be properly sterilized for clean-flow applications. For optimal cleaning of CORRTEF the tube should be stretched to its maximum length and held vertically (direction of flow: down). NOTE: Due to the annular corrugations, it may not be possible to remove all traces of particulate from CORRTEF, even under optimal cleaning conditions.

 

^Overbraiding with Kevlar® will permit a minimum increase of 6X the listed pressures. Kevlar overbraiding is available for sizes up to 7/8” I.D. – call for details.

*Workable I.D. length of the cuff. All lengths will be supplied with ‘B’ dimension cuffs (straight ends).
All pressures are calculated and not based on actual testing.
ID is the critical dimension for fittings application.
