Standard Flex Convoluted PTFE Tubing • 81914/1 

Convoluted PTFE Tubing ( SAE-AS81914/1, AMS-T-81914/1 or M81914/1 ) is engineered to be an equivalent to that of Corrugated FEP Tubing where sharp turns and small band diameters are needed. It can be used as an electrical or fluid conduit in the semiconductor industry. PTFE Convoluted Tubing will operate in applications where high temperatures are required and other materials are not suitable. Aerospace Industry often utilize the properties of PTFE Tubing for wire harness and cable protection in production and maintenance of engines. PTFE and FEP Tubing and resins are FDA approved materials and can also be used in food and medical industry.

Mil-Spec Convoluted PTFE Tubing is a high temperature material that has a non-stick surface, allowing easy cleaning and because of it smooth rounded spherical twist design convoluted tubing is self draining. PTFE is the slipperiest solid available and allows unrestricted flow without deposit build up. Mil-Spec Convo PTFE is an excellent electrical insulator and resist most corrosive liquids including hot acids.

PTFE Tubing for wire harness
  • Convoluted PTFE Tubing can be reinforced with stainless steel wire on the O.D.
  • PTFE has the best flex-life and can be post formed with cuffs easier than FEP or PFA.
  • Recommended for higher temperature and pressure applications.
  • Convo PTFE available in Black / NaturalConductive ID Tubing is also available in PTFE.
  • Extra Flex Convoluted PTFE Tubing • M81914/2

Because PTFE convoluted hose has such a low co-efficient of friction it offers a material that when used will reduce load and drag in bearings to improve efficiency and reduce frictional losses and PTFE convoluted hose will outlast other materials. PTFE convoluted hose will set due to compression, PTFE convoluted hose will conform to mating components resulting in excellent sealing capacity. PTFE convoluted hose is resistant to most acids allowing this material to be used in aggressive environments to where such materials as Polypropylene are unacceptable.
