English
Rectangular cross-section. Consists of two spiral windings which are cut at the ends at an angle of 30° or 45°. Designed for static and dynamic use, but when used in a dynamic application they should be used for reciprocating movements only. Compensates for large temperature changes and tolerances due to screw-like elongation and contraction. Material: PTFE

Basic Material:
PTFE
Commercial Description:
Unfilled PTFE. This material is standard for back-up rings. Unfilled PTFE helps prevent extrusion in low- to medium-duty applications where an O-ring used by itself would not be suitable.
