Description
Oil Cooler Sandwich Plate O-Ring — 30 × 3.5 mm
This O-ring is a precision sealing component used in Honda engine assemblies where a larger oil seal is required, often found in oil pump housings, tensioner covers, and other engine systems where reliable fluid sealing is critical. Its exact dimensions and resilient material help maintain sealing integrity under heat, pressure, and vibration, reducing the risk of oil leaks in high-stress areas.
Over time, exposure to engine heat and oil can cause O-rings to harden, crack, or lose elasticity. Replacing this seal during engine service, rebuilds, or component removal helps ensure consistent performance and prevents fluid seepage around mating surfaces.
Manufactured to factory specifications for size, material, and durability, this O-ring is appropriate for proper maintenance and restoration applications.
