The Multiquip 5126 90 Degree Coupler is a genuine OEM replacement designed for LS400, LS500, and LS600 hydraulic-driven concrete pumps and WBH series power buggies. As a direct OEM component sourced through Multiquip's authorized parts program, this coupler is built to the same specifications as the original hardware installed at the factory. Confirmed fitment includes the LS400, LS500, LS600, WBH-16, WBH-16E, WBH-16EF, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, and WBH21EPA. DHS Equipment supplies this part direct, so you can be confident you're getting the right component for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and thread specifications, ensuring the coupler seats and seals correctly under hydraulic pressure.
- 90-Degree Angle Routing — Purpose-built 90-degree configuration routes hydraulic or fluid lines cleanly through tight spaces without stressing hoses or fittings.
- Broad Fitment Coverage — Compatible with LS400, LS500, LS600 concrete pumps and the full WBH power buggy lineup, including AWD and foam-fill variants.
- Drop-In Replacement — Matches the original port size, thread pitch, and bend radius so the coupler installs directly into the existing connection point.
- Leak-Free Hydraulic Integrity — A correctly fitted coupler maintains system pressure and prevents fluid loss that can cause sluggish operation or hydraulic component damage.
- Pressure-Rated for Demanding Applications — Built to handle the operating pressures of Multiquip's concrete pump and power buggy hydraulic circuits without deformation or weeping.
A 90 degree coupler is a rigid angled fitting used to connect hydraulic or fluid lines at a right angle, allowing hoses and hard lines to change direction cleanly within the machine's frame or hydraulic circuit. This type of fitting is critical in confined equipment layouts where a straight connection would create hose kinking, excessive tension, or interference with moving components. When a coupler cracks, strips, or begins to weep fluid, it compromises system pressure and can lead to erratic machine response, hydraulic fluid loss, or a complete loss of function in the circuit it serves.
