Multiquip EM512212 Discharge Nipple

The Multiquip EM512212 is a genuine OEM Discharge Nipple designed for Mayco hydraulic-driven concrete pumps across the LS300, LS300P, LS300G, LS300GK, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, and LS60TD series. As a direct OEM replacement, the EM512212 is manufactured to the same specifications as the original component, ensuring a proper connection at the discharge point with no fitment concerns. Sourcing a genuine Multiquip part means you get the exact geometry and thread specification the pump was engineered around, keeping your concrete delivery line running at full output.

Key Features

• Genuine OEM Construction — Manufactured to the original design specification for the LS-series concrete pump discharge outlet, with correct thread form and port dimensions to maintain rated flow capacity.
• Direct-Fit Replacement — Threads directly into the pump discharge port as the original did, requiring no modification to hose couplings, clamps, or adjacent fittings.
• Broad LS-Series Compatibility — Confirmed fitment across LS300, LS300P, LS300G, LS300GK, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, and LS60TD Mayco concrete pumps.
• Pressure-Rated Discharge Connection — Built to handle the hydraulic pressure demands of continuous concrete pumping operations, maintaining a leak-free seal at the pump outlet under working load.
• Protects Downstream Components — A correctly seated discharge nipple prevents pressure loss and protects hose fittings and clamps from uneven stress caused by a worn or damaged outlet connection.

The discharge nipple is the threaded fitting at the outlet port of the concrete pump where the delivery hose or pipeline attaches. It provides the mechanical connection point through which mixed concrete exits the pump body under pressure and travels through the line to the placement area. When this fitting is cracked, cross-threaded, or worn, the seal at the discharge point breaks down, causing pressure loss, leaking slurry, and potential damage to hose couplings — any of which can interrupt a pour and require immediate shutdown to address.
