Key Features

• Genuine OEM Construction — Manufactured to Multiquip's exact Schedule 40 pipe coupling specification, ensuring correct wall thickness and thread engagement for a secure, sealed joint.
• Correct Half-Coupling Profile — Half-coupling design allows direct connection to existing pipe runs on the machine without additional fittings or adapters.
• Verified Fitment for STXD6i and HTXD6i — Purpose-built for Multiquip's hydrostatic ride-on power trowel models, so compatibility is confirmed before the part ships.
• Black Sch 40 Rating — The Schedule 40 pressure rating and black pipe finish meet the fluid-handling demands of the trowel's hydraulic or water-circuit routing where this coupling is applied.
• Direct OEM Replacement — Matches the original part number EM23872 exactly, dropping into the existing connection point without rework to surrounding plumbing.

A half coupling is a short pipe fitting with internal threads on one end, used to join a pipe to another component or to extend a pipe run. In a ride-on power trowel such as the STXD6i and HTXD6i, couplings like this one are used within the machine's fluid routing system to maintain sealed, pressure-rated connections between plumbing circuits. A worn, cracked, or incorrectly sized coupling can result in fluid leaks that compromise hydraulic performance and may cause the machine to lose blade control or drive response, making timely replacement essential to safe operation.
