Multiquip EM25509 Straight Fitting

The Multiquip EM25509 Straight Fitting is a genuine OEM component designed for LS400, LS500, and LS600 hydraulic-driven concrete pumps. Sourced directly from Multiquip, this fitting delivers the exact thread form, bore diameter, and sealing geometry required by the original equipment — no improvising, no adapting. It is confirmed compatible with the LS400, LS500, and LS600 pump series, making it a straightforward replacement when a fitting is damaged, corroded, or leaking.

Key Features

• Genuine OEM Hydraulic Integrity — Manufactured to the same pressure ratings and thread specifications as the original, ensuring leak-free connections in demanding hydraulic or fluid-line circuits.
• Inline Straight Configuration — The straight body routes fluid or hydraulic line connections without angular offset, dropping directly into the existing port without repositioning hoses or lines.
• Confirmed Fitment for LS-Series Concrete Pumps — Verified for LS400, LS500, and LS600 hydraulic-driven concrete pump models, so you can order with confidence.
• Protects Pump Circuit Performance — A failed or leaking fitting can disrupt hydraulic pressure or material flow, leading to inconsistent pump output. A correct replacement restores full system integrity.
• Corrosion-Resistant Construction — Built to withstand the wet, abrasive environment of concrete pumping operations, where fittings are routinely exposed to slurry, wash water, and mechanical stress.

A straight fitting is a fixed-path connector used to join two fluid or hydraulic lines in a direct, in-line orientation within the pump's hydraulic or fluid circuit. On concrete pumps like the LS-series, these fittings play a critical role in maintaining sealed, pressure-rated connections throughout the hydraulic drive system. When a fitting cracks, strips, or begins to seep fluid, it compromises circuit pressure and can lead to erratic pump behavior or fluid loss — making prompt replacement essential to keeping the machine operating correctly.
