Multiquip ET00278 Gauge AC110 Washer

The Multiquip ET00278 Gauge AC110 Washer is a genuine OEM component designed for the Multiquip AC110 series. Sourced directly from Multiquip, this washer delivers an exact match to the original part, ensuring a correct, secure installation without the guesswork of adapting a non-spec alternative. If your AC110 gauge assembly is leaking, loose, or showing wear around the mounting point, ET00278 is the specified replacement to restore proper function.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the exact material grade and dimensional spec required for a leak-free gauge connection on the AC110.
• Direct-Fit Installation — Matches the original mounting profile of the gauge assembly, dropping into place without trimming or shimming.
• Confirmed AC110 Fitment — Verified for the Multiquip AC110, so you can order with confidence knowing this is the correct washer for that gauge position.
• Maintains Gauge Accuracy — A properly seated washer prevents micro-movement and pressure bleed-off at the gauge port, keeping readings stable and trustworthy.
• Fuel and Fluid System Safety — On gauge connections exposed to pressurized fluid or fuel lines, a correctly spec'd washer is essential to prevent seepage and maintain a safe operating environment.

A gauge washer serves as the sealing interface between the gauge fitting and its mounting port, compressing under torque to form a fluid-tight barrier. Without a properly functioning washer, the connection can weep fluid or allow air infiltration, which leads to inaccurate gauge readings and potential system contamination. Over time, washers harden, crack, or deform — replacing a worn washer with the correct OEM part restores a reliable seal and protects the integrity of the gauge reading.
