The Multiquip 1112 Drain Plug is a genuine OEM component designed for a wide range of Multiquip and Whiteman equipment, including HTN and HHN series ride-on power trowels, C30HDNI concrete pumps, FX series concrete vibrators, and J36E2 walk-behind trowels. As an OEM part, the 1112 is manufactured to the exact specifications of the original, ensuring a correct seal and consistent fit every time. This drain plug is a direct replacement for the original part across all compatible models, including HTN28K, HTN27K, HHN34TVD, HHN31V, and FX50G6, among others. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence knowing you are receiving the correct component.
Key Features
- OEM-Grade Sealing Material — Manufactured to original thread pitch and material spec, ensuring a leak-free seal without the risk of cross-threading or weeping associated with non-matched replacements.
- Drop-In Thread Compatibility — Matches the original drain port threading on compatible trowel crankcases, pump housings, and vibrator units for a straightforward, tool-standard installation.
- Broad Fitment Across Multiple Equipment Families — Confirmed fit for HTN and HHN ride-on trowels, C30HDNI concrete pumps, FX and FXA series vibrators, and J36E2 walk-behind trowels.
- Prevents Fluid Loss During Service — A properly seated drain plug keeps engine oil or fluid fully contained between service intervals, protecting internal components from running dry.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, the 1112 carries the same part number used in the original equipment build, eliminating any guesswork on compatibility.
A drain plug seals the drain port on an engine crankcase, gearbox, or fluid reservoir, keeping oil or hydraulic fluid contained during normal operation. It is removed during scheduled fluid changes to allow old fluid to drain fully, then reinstalled to seal the system before refilling. A damaged, stripped, or missing drain plug leads to fluid leaks that can quickly deplete lubrication levels, causing accelerated wear or outright mechanical failure in the components it protects.
