Key Features

• Genuine OEM Sealing Integrity — Factory-engineered to maintain a proper airtight seal on the oil fill port, preventing contamination and oil loss during operation.
• Direct-Fit Replacement — Designed to thread directly onto the original oil fill port with the same pitch and seat geometry as the factory cap, ensuring a secure, leak-free connection.
• Broad Multiquip Compatibility — Fits across multiple Multiquip equipment families, including MVC plate compactors, WM and MC series mixers, MRH rollers, QP centrifugal and trash pumps, GAW welders, GA generators, and MP masonry saws.
• Engine Oil Protection — A correctly seated oil filler cap prevents dirt, debris, and moisture from entering the crankcase — directly protecting engine longevity and oil quality between service intervals.
• Verified OEM Part Number — Part number 15600ZG4003 is confirmed against Multiquip OEM parts documentation, so you can order with confidence that you are receiving the correct assembly.

The oil filler cap assembly seals the engine's oil fill port after servicing or topping off engine oil. Its primary role is to prevent foreign material — dust, water, and debris — from entering the crankcase while also maintaining crankcase pressure within normal operating parameters. A cracked, missing, or improperly seated filler cap can allow contamination into the oil system, leading to accelerated internal engine wear, oil consumption, or leakage — issues that often go unnoticed until significant damage has already occurred.
