Multiquip EM23851 Reducer 2"x1.5"x12" GXG

The Multiquip EM23851 Reducer 2"x1.5"x12" GXG is a genuine OEM component designed for HHNG5 and EHHNK5 series ride-on power trowels. As a direct factory replacement, EM23851 is built to the same specifications as the original part, ensuring a correct fit within the machine's plumbing or fluid transfer system. This part is compatible with both the Whiteman HHNG5 and International EHHNK5 ride-on trowel configurations, making it a reliable choice when servicing either machine. Order with confidence knowing you're installing the exact part Multiquip specifies for these units.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards for this reducer size and GXG configuration.
• Correct 2"x1.5"x12" Dimensions — Matches the original stepped reducer geometry exactly, ensuring proper thread engagement and leak-free connections at installation.
• Verified Fitment for HHNG5 and EHHNK5 — Confirmed for Whiteman HHNG5 and International EHHNK5 ride-on power trowel models.
• Maintains Fluid System Integrity — A correctly sized reducer keeps hydraulic or fluid lines properly coupled; an incorrect or worn reducer can cause pressure loss or leaks that compromise trowel operation.
• Direct OEM Replacement — Sourced directly from Multiquip, so the part installs in the same position and connects to the same fittings as the original without adaptation.

A reducer is a pipe or fitting component that transitions a fluid or hydraulic line from one diameter to another — in this case, from a 2-inch connection down to a 1.5-inch connection across a 12-inch body length. In a ride-on power trowel, reducers like this are used within the hydraulic or fluid management circuit to maintain controlled flow between components of different port sizes. When a reducer fails — whether through thread damage, cracking, or seal deterioration — fluid pressure drops or leaks can occur, directly affecting hydraulic performance and the machine's ability to operate the trowel blades correctly.
