Key Features
- Genuine OEM Construction — Machined to original Multiquip specifications, delivering the correct thread form and sealing performance expected of a 1/4MP square head plug fitting.
- Correct Thread and Drive Profile — The 1/4MP male pipe thread and square head drive ensure proper torque application and a leak-free seal when installed in the designated port.
- Broad Verified Fitment — Compatible with HHN31V, HHNG4, HHNG5, MD82, MD105, STXDF, MVH128GH, MVH158GH, MRH800GS, LT6K series, JWN24H series, WSHE-A Series, and multiple HTN and HTO mechanical trowel variants.
- Sealing Integrity Across Fluid Systems — A correctly seated plug fitting prevents fluid leaks in hydraulic, oil, or fuel passages, maintaining system pressure and protecting internal components from contamination.
- Direct OEM Part Number Reference — Order by part number EM16185 for confidence that you are receiving the exact component specified by Multiquip for your machine.
A plug fitting is used to seal an unused or service port within a fluid-carrying system — such as a hydraulic circuit, lubrication passage, or fuel line gallery. The square head drive allows a wrench to apply consistent torque, compressing the thread seal and preventing fluid from weeping past the fitting under operating pressure. When a plug fitting is missing, cross-threaded, or cracked, the affected circuit can lose pressure or allow contamination to enter, leading to degraded hydraulic response, oil loss, or component wear. Replacing a damaged or missing plug fitting promptly restores circuit integrity and protects the downstream components it serves.
