The Multiquip EM491164 90° 1/4" Nipple is a genuine OEM fitting designed for the LS300P hydraulic-driven concrete pump. Sourced directly from Multiquip, this fitting matches the original component spec for a straightforward, drop-in replacement with no guesswork. If you're servicing or rebuilding the fluid circuit on your LS300P, EM491164 is the correct part to restore proper flow routing and connection integrity.
Key Features
- Genuine OEM Construction — Manufactured to the same thread form, angle, and material grade as the original fitting, ensuring a leak-free connection in demanding concrete pump hydraulic and fluid line applications.
- 90° Angle Routing — The right-angle profile directs fluid lines cleanly around obstructions inside the pump housing, preserving the original plumbing layout without improvised adapters.
- Direct LS300P Fitment — Confirmed for the Multiquip LS300P hydraulic-driven concrete pump, so you're ordering against a known application, not guessing at compatibility.
- Maintains Fluid Circuit Integrity — A worn, cracked, or leaking nipple can cause pressure loss or fluid contamination in the pump system; replacing with the correct OEM fitting restores consistent output and protects downstream components.
- Exact Thread Specification — 1/4" thread sizing matches the original port and mating fitting, allowing confident hand-start assembly and proper torque without cross-threading risk.
A 90° nipple is a directional pipe fitting that connects two fluid or hydraulic lines at a right angle, allowing hose and tubing runs to change direction within a confined space without sharp bends that could restrict flow or cause line fatigue. In a concrete pump like the LS300P, these fittings play a critical role in routing hydraulic or water lines cleanly through the pump frame and manifold assembly. When a nipple cracks, corrodes, or develops thread damage, it can introduce leaks that reduce hydraulic pressure, contaminate fluid, or cause the pump to lose performance — making timely replacement essential to keeping the machine operating at full output.
