Convoluted PTFE Tubing With Cuffs

Convoluted PTFE Tubing with Cuffs is a flexible tube with a spherical twist that allows for bend diameters equal to that of Corrugated FEP Tubing. Manufactured from a high temperature chemically inert Fluoropolymer resins Convoluted PTFE Tubing takes standard convoluted material and turns it into a hose with straight ends or cuffs that allow for an easy transition to barb fittings. This smooth transition in the tubing removes the convolutions which reduces bunching up of material and allows customers to use standard hose clamps for their application.

Cuffs on Convoluted Tubing are designed to have standard fractional ID’s such as 1/4″ , 1/2″ and 3/4″ all the way up to a 4” diameter. Customers can order specific custom made cuffed ID’s or even cuffed OD’s for applications and processes that are using compression fittings.

PTFE has the best flex-life and can be post formed with cuffs easier than FEP or PFA.

Convoluted PTFE can handle static dissipative & vacuum service applications

Convoluted PTFE Tubing can be reinforced with stainless steel wire on the O.D. for operations at higher pressures.

Cuffed PTFE Tubing can be made with a Conductive ID.

Convoluted PTFE Tubing has a working temperature range up to 500°F and can be made in longer lengths which gives it and advantage over Corrugated FEP Tubing which has a 12 ft limitation on length. For Applications that do require extreme flexibility Cuffed Convoluted PTFE Tubing can be made from Extra Flex Mil Spec Convo which would increase the flexibility of the hose and drastically lower the bend diameter of the tube.

Convo PTFE has a non-stick surface, allowing easy cleaning and is self draining because of it spherical design which makes it an ideal hose for caustic fluid transfer applications. Convoluted PTFE Tubing with cuffs is generally supplied in natural PTFE, but can be manufactured in black or other custom colors.
