The Multiquip HU3108 SAE Plug is a genuine OEM component designed for HTH-SERIES, HTH44T, and STH hydrostatic ride-on trowels. As a direct factory replacement, this plug meets the exact specifications required by Multiquip's hydrostatic trowel hydraulic systems, ensuring a secure, leak-free seal in the correct port location. Sourced directly through authorized Multiquip supply channels, the HU3108 is the right part to keep your machine operating to its original design standard.
Key Features
- OEM-Spec Thread and Sealing Profile — Manufactured to the exact SAE thread dimensions required for hydraulic port sealing on Multiquip hydrostatic trowels, preventing pressure loss or fluid contamination.
- Direct-Fit Hydraulic Port Replacement — Installs directly into the designated SAE port without rework, threading in cleanly to the same torque specification as the original.
- Confirmed Fitment for HTH and STH Series — Verified for use on HTH-SERIES, HTH44T, and STH hydrostatic ride-on trowels — confirm your model code before ordering.
- Hydraulic System Integrity — A properly seated SAE plug maintains system pressure and prevents external leaks that can lead to blade pitch loss, drive failure, or contamination of the hydraulic fluid.
- Fluid System Safety — Hydraulic fluid leaks on ride-on trowels create slip hazards on the slab surface; replacing a damaged or missing plug promptly keeps the work area safe.
An SAE plug is a threaded sealing fastener used to close off unused or temporarily open hydraulic ports within a machine's hydraulic circuit. On hydrostatic ride-on trowels like the HTH and STH series, the hydraulic system controls both blade pitch and machine drive, so maintaining a fully sealed circuit is critical to consistent performance. A missing, damaged, or improperly seated plug can allow fluid to escape under pressure, causing a drop in system pressure that directly affects blade responsiveness and drive control.
