Multiquip 25837 5"x4"x90° Elbow

The Multiquip 25837 5"x4"x90° Elbow is a genuine OEM concrete pump elbow designed for LS and ST series hydraulic-driven concrete pumps and SP series pavement saws. This component serves as a direct replacement for equipment including the LS40, LS40D, LS40TD, LS50TD, LS300, LS400, LS500, LS600, LS60TD, ST-70, SP303516, SP303520, SP303526, and SP303530. Sourcing the correct OEM elbow ensures your discharge line maintains proper flow geometry and pressure integrity across pump cycles. DHS Equipment supplies this part as a stocked Multiquip OEM replacement to keep your equipment running at specification.

Key Features

• OEM-Grade Material Specification — Cast to Multiquip's dimensional and material standards for concrete pump discharge applications, resisting abrasion from aggregate slurry flow.
• 90-Degree Flow Path with Reducing Geometry — The 5" inlet-to-4" outlet taper transitions flow through a full 90-degree bend, matching the designed discharge routing on LS and ST series concrete pumps.
• Broad LS and ST Series Compatibility — Confirmed fitment across LS40, LS40D, LS40TD, LS50TD, LS300, LS400, LS500, LS600, LS60TD, and ST-70 hydraulic concrete pump models.
• SP Pavement Saw Compatibility — Also fits SP303516, SP303520, SP303526, and SP303530 pavement saw models where this elbow configuration is used.
• Discharge Line Integrity — A worn or cracked elbow compromises concrete pressure and creates material loss at the bend; replacing with a correctly specified OEM elbow restores full pump output and keeps the line sealed under operating pressure.

A concrete pump elbow directs the flow of mixed concrete from the pump's discharge port through a defined change of direction before material exits at the placement point. In reducing elbows like the 25837, the inlet and outlet diameters differ, allowing the pump system to transition between pipeline sizes while maintaining flow velocity. When an elbow cracks, erodes through aggregate wear, or develops a leak at the joint, pump output drops, material can escape under pressure, and the surrounding discharge line is placed under uneven stress — making timely replacement critical to keeping pours on schedule and the pump operating safely.
