Hydraulic Seals

Y-Ring

Y-rings are lip seals with a Y-shaped cross-section designed for hydraulic and pneumatic reciprocating applications. The Y-profile creates a self-sealing effect where system pressure enhances the sealing force. Available in both piston (YX-axis) and rod (YX-hole) configurations. The fabric-reinforced variant offers improved extrusion resistance for high-pressure applications.
