Square O-Ring Kit 1.88/1 .62

The Square O-Ring Kit 1.88/1.62 by Wilwood is a vital sealing component designed for high-performance brake and hydraulic systems in both street and race vehicles. This kit is particularly beneficial for modified brake builds, where precision sealing is crucial to prevent fluid leakage and ensure system integrity under demanding conditions.

The square o-ring design features an outer diameter of 1.88 inches and an inner diameter of 1.62 inches, providing consistent sealing in bore applications. This design allows for a larger contact patch against bore walls, distributing pressure evenly and resisting extrusion under high hydraulic loads. The o-rings are typically made from materials compatible with brake fluid, ensuring thermal stability and resistance to fluid degradation.

Mechanics and automotive enthusiasts rebuilding Wilwood master cylinders, proportioning valves, and modulating valve assemblies will find this kit indispensable. Its precision manufacturing ensures dimensional tolerance that prevents bypass leakage, making installation straightforward without the risk of pinching or tearing.
