Multiquip 506218 Fitting 3/4" AR-13H - OEM Replacement Part

This 3/4" fitting is a critical hydraulic system component that connects and routes hydraulic fluid throughout the AR-13 series ride-on rollers. The fitting ensures proper hydraulic pressure distribution to key systems including the hydrostatic drive, vibration mechanism, and steering cylinders that control roller direction and compaction force.

In the AR-13 series rollers, the hydraulic system operates with ISO 46 anti-wear hydraulic fluid and is filtered through both a screen-type reservoir filter and internal system filters. This fitting maintains sealed connections within the hydraulic manifold assembly, which controls flow to various hydraulic motors and components. Failed or leaking fittings can result in loss of hydraulic pressure, reduced vibration force (rated at 3,100 lbs centrifugal force at 2,400-2,700 rpm), compromised steering response, or complete system failure.

Regular inspection of hydraulic fittings during routine maintenance helps prevent costly downtime and fluid contamination. Replace fittings showing signs of thread damage, seeping fluid, or corrosion to maintain optimal hydraulic system performance.

Compatible with the following Multiquip roller models:

• AR13D
