Square ring seals, also known as washer rings or lathe-cut rings, are a robust sealing device characterized by their square-shaped cross-section. They offer enhanced sealing performance and versatility across a wide range of applications, providing a cost-effective alternative to traditional O-rings.

They seamlessly fit into standard O-ring grooves, offering size-for-size interchangeability and compatibility with various rubber and plastic materials such as NBR, Viton, EPDM, and Teflon.

Widely used in automotive, industrial, and manufacturing sectors. They excel in sealing hose and pipe connections, hydraulic systems, pumps, valves, and mechanical assemblies where reliable sealing under pressure is crucial. They provide a cost-effective sealing solution without requiring design modifications, making them ideal for retrofitting existing systems.
