Multiquip EM211 Plug Fitting 1/8MP Hex Socket Head

The Multiquip EM211 is a genuine OEM Plug Fitting 1/8MP Hex Socket Head designed for a wide range of Multiquip and Whiteman power trowels, roller screeds, walk-behind rollers, and flat saws. As a direct OEM part, EM211 meets the exact material and dimensional standards set for the original hydraulic and fluid system ports on these machines. Verified fitment includes hydrostatic ride-on trowels such as the MD80, MD105, HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STXD6i, and STXDF, as well as walk-behind trowel models including the B46, HDA Series, JH55C, JH90C, JS60C, and many additional Whiteman and international series units. The WRS5200, WRS5200DFPU, and WRSPUDF roller screeds, MRH800GS walk-behind roller, and SP1G and SP2S20H flat saws are also covered fitments.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the exact thread specification and hex socket drive dimensions required for a leak-free port closure on hydraulic and fluid systems.
• Hex Socket Drive Design — The internal hex socket head allows precise torque application in tight engine bays and hydraulic compartments without rounding or slippage.
• Broad Trowel Family Coverage — Fits MD, HTX44, STX55, LD, and STXDF hydrostatic ride-on trowel series, plus Whiteman and international walk-behind models including B46, HDA, and JS36 variants.
• Correct Port Thread Sizing — The 1/8 MP (male pipe) thread matches the original port specification, ensuring a secure, compatible connection without re-tapping or adapter fittings.
• Fluid System Reliability — A properly seated plug fitting prevents hydraulic fluid or oil leaks that can lead to pressure loss, contaminated work surfaces, and premature pump or motor wear.
• Multi-Equipment Versatility — Also fits the WRS5200 roller screed series, MRH800GS walk-behind roller, and SP-series flat saws, making EM211 a practical stocking part across multiple machine types.

A plug fitting is a threaded closure used to seal unused or temporary access ports in hydraulic circuits, oil passages, and fluid system housings. The 1/8 MP hex socket head design allows the fitting to be installed and removed using a hex key, making it well suited for recessed or space-constrained port locations. When a plug fitting is missing, damaged, or cross-threaded, the open port allows fluid to escape, air to enter the system, or contaminants to reach sensitive hydraulic components — any of which can cause pressure loss or accelerated internal wear. Keeping the correct fitting installed and properly torqued is a straightforward but critical step in maintaining hydraulic system integrity across trowel, screed, roller, and saw applications.
