Type BP (Spiral)
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
Size Range:
5 mm to 115 mm
Temperature:
-200 °C to 260 °C
Pressure (max):
25 MPa
Material Information for the product(s) on this page
PT00
Colour:
White to Offwhite
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.
