Design
  • Single acting buffer seal with anti-extrsion ring.
  • Used in conjunction with a primary rod seal.
  • Absorbs shock pressure and protects the primary seal.
  • Can tolerate higher extrusion gaps.
Material
  • PU92A Polyurethane with low compresison set, high modulus of elasticity and excellent resistance to wear.
  • NBR energiser.
  • Acetal anti-extrusion ring.
Application
  • Single acting rod seal normally used in tandem.
  • Used as a buffer seal.
Fluids
  • Hydraulic fluids, petroleum fuels and oils
