	Item # 340 0229, Corrtef® Corrugated FEP Tubing
	List Price QUOTE

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 from FDA-sanctioned ingredients
Made without plasticizers which can leach into critical streams
Has all the chemical and electrical properties of straight-walled FEP tubing
May be over braided with Kevlar® for higher pressures. (Over braiding with Kevlar will permit a minimum increase of six times the listed pressures. Kevlar over braiding is available for sizes up to 7/8" I.D.)

Notes

Vacuum Service: 29.9 in./Hg.
Bend Diameter: 1/2 of tubing I.D.
Extension/Compression Length Ratio: 2 to 1

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

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 dean-flow applications. For optimal cleaning of CORRTEF, the tube should be stretched to its maximum length and held vertically (direction of flow: down). Due to the annular corrugations, it may not be possible to remove all traces of particulate from CORRTEF, even under optimal cleaning conditions.
