The Multiquip HU3182 SAE Plug is a genuine OEM component designed for HTH-SERIES, HTH44T, and STH hydrostatic ride-on trowels. As a direct OEM replacement, this plug meets the same specifications as the original part installed at the factory, ensuring a correct fit within the hydraulic system. Sourced directly through authorized Multiquip distribution, part number HU3182 is the right call when you need a dependable, verified replacement for these trowel families.
Key Features
- Genuine OEM Construction — Manufactured to the original specification for the hydraulic system on hydrostatic ride-on trowels, with no guesswork on thread form or sealing interface.
- SAE-Standard Thread Form — Engineered to SAE port dimensions, ensuring a consistent, leak-free seal when torqued to spec in compatible hydraulic fittings and ports.
- Confirmed Fitment — Verified for HTH-SERIES, HTH44T, and STH hydrostatic ride-on trowel models, so you can order with confidence using part number HU3182.
- Hydraulic Integrity — A correctly seated SAE plug maintains system pressure and prevents fluid loss; a missing or damaged plug can cause immediate hydraulic pressure drop and trowel control failure.
- Direct Installation — Installs into standard SAE ports without additional adapters or modifications to existing hydraulic plumbing on supported models.
An SAE plug is used to seal unused or temporarily open hydraulic ports within a machine's hydraulic circuit. On hydrostatic ride-on trowels like the HTH-SERIES and STH, maintaining a fully sealed hydraulic system is critical to consistent blade pitch control and drive response. A missing, cross-threaded, or damaged plug can allow hydraulic fluid to escape or contaminants to enter the circuit, leading to erratic trowel behavior or system pressure loss during finishing operations.
