Multiquip 50640500 Crankcase Breather Filter

The Multiquip 50640500 is a genuine OEM Crankcase Breather Filter designed for MQ600H, MQ600HTB, and MQ600HTP trash pumps. Sourced directly from Multiquip, this filter carries the same specifications as the component installed at the factory, ensuring a drop-in fit without guesswork. It is a direct match for the MQ600H trash pump family, confirming compatibility across all three variants in that series. When you need to keep your equipment running clean and on schedule, specifying the correct OEM 50640500 is the fastest path to a confident repair.

Key Features

• Genuine OEM Filtration Media — Manufactured to Multiquip's exact porosity and flow specifications for the MQ600H engine crankcase ventilation circuit, not a generic substitute.
• Direct-Fit Replacement — Engineered to seat correctly in the original breather housing with the stock mounting interface, so installation is straightforward with no adapters or modifications.
• Confirmed Compatibility — Verified fitment for MQ600H, MQ600HTB, and MQ600HTP Honda-powered trash pumps.
• Protects Engine Internals — A serviceable crankcase breather filter prevents blow-by contaminants and oil mist from recirculating into the intake unfiltered, which directly affects oil life and cylinder wear over time.
• Supports Routine Maintenance Intervals — Replacing this filter on schedule prevents clogging that can raise crankcase pressure, push oil past seals, and lead to costly downstream repairs.

The crankcase breather filter vents combustion blow-by gases from the engine crankcase while filtering out oil mist and airborne contaminants before those gases are routed back into the intake system. When the filter becomes clogged or deteriorated, crankcase pressure builds up, forcing oil past gaskets and seals and allowing unfiltered vapor into the combustion chamber — accelerating engine wear and increasing oil consumption. On Honda-powered trash pumps like the MQ600H series, keeping this filter clean and intact is a straightforward but critical part of protecting the engine between pump jobs.
