Performance and Purpose

This end-facing seal has a “Y”-shaped cross section. It is designed specifically for steel pipe hydrostatic testing machines to seal the plane on water filling and air exhaust test heads. When installing, ensure the two planes should be in close contact, and pay attention to the installation direction of the sealing ring.



  1. It is a sealing element consisting of a PY type face sealing and a steel skeleton.
  2. The support skeleton enhances the overall strength of the seal ring.
  3. The sealing material has the advantage of high strength, high hardness and good elasticity
