Key Features and Functions – Caterpillar MJ-367712:

• Fits Caterpillar C7/C9 engines
• Category: HPOP Gasket
• Seals between high-pressure oil pump and engine
• Prevents oil leaks under high pressure
• New aftermarket replacement available for bulk orders

2. HPOP Gasket Function and Materials Overview

High-pressure oil pump (HPOP) gaskets seal the joint between the pump and engine block in HEUI (Hydraulic Electronic Unit Injector) systems. They must maintain a tight seal under extremely high oil pressure to prevent leaks that could result in injector malfunction or loss of hydraulic control.

Because the HPOP gaskets are exposed to intense pressure, oil flow, and thermal variation, they must be made from materials that offer both structural integrity and long-term sealing performance.
Common material types include:

• Rubber
• Metal bonded with rubber
