Performance and Purpose

This end-facing seal has a “Y”-shaped cross section. It is designed specifically for steel pipe hydro-static testing machines to seal the plane on water filling and air exhaust test heads. Close contact between the two planes is required during installation, and attention should be paid to the installation direction of the sealing ring.
