PTFE-Engineered & Machined Components

PTFE (Polytetrafluoroethylene)

Commonly referred to as Teflon®, provides true chemical inertness. PTFE is unaffected by most known chemicals, including alkaline solutions, acids, and solvents, and also offers extremely low coefficients of friction. Under moderate loads, PTFE can be used in temperatures up to 500°F and in liquid nitrogen as low as -325°F.
