• Broad Cross-Equipment Compatibility — A single OEM part number covering MTX rammers, MVC and MVH plate compactors, WM mortar mixers, MC concrete mixers, CA trowels, and more.
• Oil-Change Service Essential — Replacing this washer at every oil change prevents seepage at the drain plug, protecting engine internals and keeping fluid levels accurate between services.
• Direct Multiquip OEM Part — Part number 90601ZE1000 is sourced through Multiquip's authorized parts channel, matching the original component specification exactly.

The drain plug washer is a small but critical sealing component located between the oil drain plug and the engine oil pan. Its job is to compress slightly when the plug is tightened, forming a metal-to-metal seal that prevents engine oil from leaking past the threads. Over repeated drain cycles, the washer can deform, thin out, or lose its ability to re-seal, which leads to slow oil seeps at the drain point — a problem that often goes unnoticed until oil levels drop or a surface stain appears beneath the machine. Replacing the Multiquip 90601ZE1000 Drain Plug Washer 10.2MM at every oil service is a low-cost step that protects against oil loss, engine wear, and the mess of chronic drip leaks on the jobsite.
