Multiquip EM98128 Coupler Hayes 125603 - OEM Replacement Part for Concrete Pumps

This Hayes hose coupler connects concrete delivery hoses and pump manifolds on trailer-mounted structural concrete pumps, creating a secure, leak-free seal critical for preventing concrete separation and line blockages during pumping operations. As noted in official Multiquip service documentation, leaking manifold seals or hose coupling gaskets that allow water leakage can cause material separation and subsequent jamming at the connection point—making properly functioning couplers essential for uninterrupted pumping performance.

The EM98128 Hayes 125603 coupler is engineered to maintain seal integrity during high-pressure concrete delivery, particularly important when pumping long distances or working with stiff mixes where valve efficiency and consistent flow are critical. This coupler is designed for demanding applications pumping a wide variety of concrete mix designs, from wet pours to stiffer structural mixes.

• LS-40 Structural Concrete Pump
• LS-40TD Structural Concrete Pump
