Multiquip 23275-04 4" Filter Head with Indicator 5PSI Bypass

The Multiquip 23275-04 is a genuine OEM 4" Filter Head with Indicator 5PSI Bypass designed for Whiteman ride-on power trowels including the HHXD5, HHXG5, HHXD5-ES, and HHXDF4-DF5 series. Sourced directly from Multiquip, this part meets the exact specifications of the original component it replaces. It installs as a direct replacement with no fitment guesswork, making it the right call for fleet maintenance and field repairs. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the bypass valve and indicator function exactly as intended for hydraulic filtration performance.
• Integrated Bypass Indicator — The built-in 5PSI bypass indicator provides a visible signal when the filter element is approaching restriction, supporting proactive maintenance on the hydraulic system.
• Direct-Fit Replacement — Engineered to match the original 4" filter head port configuration and mounting interface on compatible Whiteman ride-on trowels, so installation is straightforward.
• Confirmed Fitment — Compatible with HHXD5, HHXG5, HHXD5-ES, and HHXDF4-DF5 Whiteman ride-on power trowels.
• Hydraulic System Protection — A properly functioning filter head maintains correct oil flow and bypass pressure, protecting downstream hydraulic components from contamination and pressure spikes.
• Fuel and Fluid System Safety — The 5PSI bypass rating is a critical design parameter; using the correct OEM-spec head ensures the bypass valve opens at the right threshold, preventing filter collapse or unfiltered flow.

The filter head is the housing assembly that secures the filter element in the hydraulic circuit and controls oil flow through and around the filter media. The integrated bypass valve allows oil to route around a clogged or over-pressurized filter element at a set threshold — in this case 5PSI — preventing starvation to hydraulic actuators and drive components. The indicator signals when that bypass condition is active, alerting the operator that the filter element needs servicing. A damaged or leaking filter head can cause unfiltered oil to circulate through the hydraulic system, accelerating wear on pumps, motors, and control valves.
