8B-1615 8B1615 GASKET Parts 955K 955L 935C

‌Q: What's the fuction of  8B-1615 ?‌
‌A: The primary function of the 8B1615 gasket is to create a tight, leak-proof seal between a fluid pump (most commonly the engine oil pump or water pump) and the engine block or fluid lines.Because it operates in heavy-duty environments, its job breaks down into three main functions:

• Preventing Fluid Leaks: It stops pressurized engine oil or coolant from seeping out of the joint where the pump connects to the system.
• Preventing Air Suction: On the intake side of a pump, a bad seal can allow air to be sucked into the system. If air gets into an oil pump, it causes cavitation and a drop in oil pressure, which can destroy an engine. This gasket ensures only pure fluid is drawn in.
• Conforming to Imperfections: Even though metal mating surfaces look flat, they have microscopic imperfections. Under the pressure of the bolts, this 0.8mm compressible gasket crushes slightly to fill those microscopic gaps perfectly.

‌Q: Should we treat 8B1615 as a standard gasket in procurement?‌
‌A: Only if specs match sealing requirements (pressure, temp, media). Always verify against the drawing — some “8B1615” parts may be custom retainers or spacers mislabeled as gaskets.
