Product Description:
Grayline PTFE-CON tubing is made from a semi-rigid, high temperature, fluoropolymer resin that offers outstanding chemical, electrical, and temperature resistance. The U.S. Food and Drug Administration sanctions all ingredients in this product for use in food contact applications. PTFE-CON has a spiral construction that allows easy cleaning and far greater flexibility than straight wall tubing. Optional wire coils provide increased pressure capability and aid in electrical grounding. For high vacuum applications, PTFE-CON can be produced with wire on the ID. The cuffs (straight ends) are made to accept standard barbed fittings.
