Product Description
The 76159 is an oil relief valve for aircraft piston engine lubrication systems. This spring-and-plunger assembly regulates oil pressure by bypassing excess flow back to the sump, protecting engine bearings from overpressure during high-RPM operation and temperature changes. Installed downstream of the oil filter, the valve maintains consistent pressure across varying flight conditions.
Adjustment capability allows technicians to set the relief threshold per engine specifications. Verify compatibility with your engine's Illustrated Parts Catalog before installation and follow the applicable engine maintenance manual for proper setup and testing.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
