2107-119 PTFE SPIRAL B/U FDA

This back-up ring is supplied in AS568-119 white PTFE (Teflon) 55 Shore D built to an inside diameter of 0.924 in (23.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.13 in (28.7 mm), catalogued under part number TSP119. It allows a standard o-ring to operate at higher pressures than it could unsupported.

PTFE (Teflon) is known for a very wide continuous service temperature range and one of the lowest coefficients of friction of any solid. Expect good resistance to solvents, nearly all industrial chemicals, and strong acids and bases. The material carries a published service range of -65°F (-53.9°C) to 500°F (260°C). Applications involving molten alkali metals or service requiring elastic recovery call for a different compound.

Maintenance and OEM teams specify it across laboratory equipment, aggressive-media pipelines, and chemical processing.

This item is sold individually under part number TSP119. Check the compound against your process media, pressure and temperature before committing to a design.
