The Multiquip EM25511 Straight Fitting 4 F5OX-S is a genuine OEM hydraulic fitting designed for WTB-16PD and WTB-16 power buggies as well as Mayco concrete pump models including C30HDZ, LS40D, LS40TD, LS50TD, LS400, and LS500. As an authentic Multiquip OEM component, it is manufactured to the exact thread form, seat angle, and port dimensions required for a secure, leak-free connection. Sourced directly through authorized distribution channels, EM25511 ensures you are installing the same fitting that left the factory — with no guesswork on compatibility. DHS Equipment stocks this part ready for order to keep your equipment on schedule.
Key Features
- OEM Thread and Port Precision — Manufactured to exact thread form and seat geometry, eliminating the risk of cross-threading or hydraulic weeping at the connection point.
- Straight-Through Flow Path — The inline straight configuration maintains full flow efficiency in hydraulic or fluid lines, avoiding the pressure drop associated with angled or offset fittings.
- Broad Multiquip Fitment — Confirmed for WTB-16PD, WTB-16, C30HDZ, LS40D, LS40TD, LS50TD, LS400, and LS500 models, spanning both the power buggy and Mayco concrete pump product lines.
- Leak-Free Service Life — Proper seating of a correctly spec'd fitting prevents fluid loss that can cause hydraulic pressure drops, contamination, and component damage downstream.
- Genuine OEM Replacement — Carrying the Multiquip OEM designation means this fitting meets the same material and dimensional standards as the original, not a field approximation.
A straight hydraulic fitting serves as a fixed-thread inline connector that joins two fluid-carrying lines or ports in a hydraulic or plumbing circuit. Its job is to create a pressure-tight seal between components while maintaining an unobstructed flow path. When a fitting corrodes, cracks, or strips its threads, it introduces the risk of hydraulic fluid leaks that reduce system pressure, cause erratic machine response, and can create a fluid hazard on the worksite. Replacing a damaged fitting promptly with the correct OEM part restores circuit integrity and protects the surrounding hoses, seals, and valve bodies from secondary damage caused by pressure fluctuation or contamination.
