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

Seal Capabilities

  • Size Range: 5 mm to 115 mm
  • Temperature: -200 °C to 260 °C
  • Pressure (max): 25 MPa
