Tefzel ETFE Tubing
Tefzel (ETFE) tubing has some outstanding properties which makes it particularly suitable for HPLC since it has a higher burst pressure when compared to Teflon. The most common dimension is 1/16" x 0.25 mm which will withstand up to 186 bar (2700 psi) using water as mobile phase.
It is important, however, to note that when using Tefzel with organic solvents it may swell and will reduce the max. pressure to 70 bar (1000 psi). Tefzel is the ideal polymer with regard to interaction with chloride salts, which typically corrode stainless steel but not
