Round O-Ring Kit - 2.38

The Round O-Ring Kit - 2.38 from Wilwood is a precision hydraulic seal component designed for high-performance brake and clutch systems. This kit is essential for mechanics working on modified vehicles, as o-ring degradation can quickly compromise brake line integrity and fluid pressure retention.

This kit addresses critical maintenance needs by replacing worn or damaged seals in Wilwood's caliper and master cylinder assemblies. The seals are manufactured to strict OEM tolerances, ensuring a perfect fit and reliable performance. They are typically made from high-grade synthetic rubber or EPDM compounds, which are resistant to DOT-approved brake fluids and thermal cycling.

Whether you're restoring a street car or maintaining a race vehicle, having quality replacement o-rings on hand prevents costly downtime. The 2.38-inch designation refers to the inside diameter of the round seal profile, making it compatible with specific Wilwood calipers and master cylinders in that size range.
