Multiquip 22370 Filter Housing 5Psi Bypass

The Multiquip 22370 Filter Housing 5Psi Bypass is a genuine OEM component designed for STXD6i and HTXD6i Whiteman ride-on power trowels. Sourced directly from Multiquip, this part meets the exact specifications of the original component it replaces, ensuring a correct, trouble-free installation. Whether you are performing scheduled maintenance or replacing a damaged housing, part number 22370 restores the hydraulic filtration system to proper operating condition.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the bypass valve seats and housing threads mate correctly with the existing filtration assembly.
• Calibrated 5 PSI Bypass — The integrated bypass valve opens at the correct 5 PSI differential, protecting the hydraulic system from pressure spikes without allowing unfiltered fluid to circulate under normal operating conditions.
• Direct-Fit Replacement — Engineered specifically for the STXD6i and HTXD6i hydrostatic ride-on trowel platform, dropping into the existing mounting position without alteration.
• Protects Hydraulic Components Downstream — A properly functioning filter housing keeps contaminants out of the hydraulic circuit, extending the service life of pumps, motors, and control valves on the trowel.
• Verified Multiquip Part Number — Ordering by part number 22370 confirms you are receiving the correct housing for your machine, eliminating guesswork during a service event.

The filter housing on a hydrostatic ride-on trowel contains and supports the hydraulic oil filter element while providing a sealed path for fluid to flow through the filtration circuit. The 5 PSI bypass valve built into the housing serves as a pressure-relief safeguard — if the filter becomes restricted, the bypass opens to maintain hydraulic flow and prevent pump cavitation or starvation. When the housing cracks, threads strip, or the bypass valve fails to seat correctly, unfiltered fluid can enter the system or pressure regulation is lost, accelerating wear throughout the hydraulic drive and blade-pitch control components.
