Multiquip EM911064 Pipe 1/2 Square Head Plug

The Multiquip EM911064 Pipe 1/2 Square Head Plug is a genuine OEM component designed for Whiteman and International ride-on power trowel models including HHN31V, HHN34TVD, HHXD5, HHXG5, HHXD5-ES, EHHNK5, HHXDF4-DF5, and HHNG5. Sourced directly from Multiquip, this plug is manufactured to the same specifications as the original part installed at the factory. Verified fitment across the HHN and HHX series means you can order with confidence knowing EM911064 is the correct replacement for your machine.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specifications, ensuring a proper seal without improvised substitutes that may weep or fail under pressure.
• Direct Drop-In Replacement — The 1/2 square head drive profile installs with standard tools and seats correctly in the threaded port without additional hardware or modification.
• Broad Ride-On Trowel Compatibility — Confirmed fitment for HHN31V, HHN34TVD, HHXD5, HHXG5, HHXD5-ES, EHHNK5, HHXDF4-DF5, and HHNG5 ride-on power trowels.
• Fluid System Integrity — A correctly seated pipe plug prevents fluid loss from the hydraulic or engine circuit, keeping system pressure stable and protecting downstream components from contamination or dry-running damage.
• Leak Prevention at Critical Ports — Plug failure or an incorrect substitute can result in fluid weeping at the port, which poses a fire and slip hazard on an active pour site — making an exact OEM replacement the right choice here.

A pipe plug seals an unused or service-access port in a fluid-carrying circuit — whether hydraulic, lubrication, or coolant — preventing leaks and maintaining system pressure. On ride-on power trowels like the HHN and HHX series, these ports are found throughout the hydraulic drive and blade-pitch systems where maintaining fluid containment is critical to consistent blade control and machine responsiveness. When a plug fails, strips, or is replaced with an incorrect size, the resulting leak can cause pressure loss, fluid contamination, and potential damage to pumps or motors that depend on a sealed circuit to function correctly.
