Key Features
- OEM-Spec Hydraulic Sealing — Manufactured to Multiquip's original pressure ratings and thread specifications, ensuring leak-free performance at the fitting junction.
- 90° Elbow Configuration — The angled design allows hydraulic lines to route cleanly around tight corners and chassis obstructions without kinking or stressing the hose.
- Direct Replacement Fit — Matches the original 6-4 C5OX-S specification, threading directly into the existing port with no machining or adaptation needed.
- Broad Multiquip Fitment — Compatible across the WTB-16, WBH-16, WBH-21, and LS300 series, covering a wide range of Whiteman power buggies and Mayco concrete pumps.
- Hydraulic System Integrity — A worn or leaking elbow fitting can cause pressure loss and erratic hydraulic response; replacing with a genuine OEM part restores consistent system pressure and control.
A 90° elbow fitting serves as a directional connector within a hydraulic system, allowing fluid lines to change direction at a right angle without placing stress on hoses or adjacent components. In power buggies and concrete pumps, these fittings are critical to maintaining consistent hydraulic pressure throughout the drive and lift circuits. When a fitting develops a leak or the threads become damaged, hydraulic pressure drops, leading to sluggish or unpredictable machine response — making timely replacement essential to keeping the hydraulic system operating correctly.
