The Multiquip 506203 is a genuine OEM Fitting designed for AR13-series asphalt ride-on rollers and WBH-series hydraulic power buggies. Sourced directly from Multiquip, this fitting delivers the exact dimensional tolerances and material grade required for a secure, leak-free connection in hydraulic and fluid line applications. Confirmed fitment covers AR13HC, AR13HA/HAR, AR13H, and AR13D roller models, as well as WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, and WBH-21EF power buggies. When you need a straight swap with no guesswork, part number 506203 is the correct OEM choice.
Key Features
- Genuine OEM Specification — Manufactured to Multiquip's original thread pitch, port sizing, and sealing surface tolerances, ensuring a fluid-tight connection every time.
- Drop-In Replacement — Matches the original mounting configuration and port geometry, so installation seats correctly without reworking lines or adapters.
- Broad Fitment Coverage — Fits AR13HC, AR13HA/HAR, AR13H, and AR13D rollers, plus WBH-16, WBH-16E, WBH-16EF, WBH-16F, WBH-16EAWD, WBH-16EAWDF, and WBH-21EF power buggies.
- Hydraulic Integrity — A properly seated fitting maintains system pressure and flow, preventing fluid loss that can starve hydraulic circuits and cause erratic or failed machine operation.
- Fluid-System Safety — Correct thread engagement and sealing prevent pressurized hydraulic fluid leaks, protecting operators and bystanders from high-pressure fluid hazards.
A fitting serves as a threaded connection point within a machine's hydraulic or fluid delivery system, joining hoses, lines, or ports so fluid can move between components under pressure. When a fitting is cracked, cross-threaded, or corroded, it creates leak points that bleed pressure from the system — leading to sluggish hydraulic response, fluid contamination, and potential component damage. Replacing a worn or damaged fitting with the correct OEM part restores a sealed, pressure-rated connection and keeps the hydraulic circuit operating as intended.
