Not only can this Teflon® PTFE tubing handle a wide temperature range, it also has a convoluted spiral design for good flexibility and smooth flow. It has a cuff on each end for smooth connections. Connect tubing to fittings with a worm-drive clamp (sold separately). Tubing has the chemical resistance to withstand a wide range of acids and other harsh substances. It meets USP Class IV for material testing; it is not for use in medical applications. Tubing meets UL 94 V-0 for flame retardance, so it delays the spread of flames to valuable equipment. It is semi-clear, so it gives you a limited view inside your line.
