The Multiquip EM491160 Pipe Plug 1" NPT is a genuine OEM component designed for Essick stationary mixer and Whiteman track buggie models including the PRO12, PRO12E51, PRO12E53, PRO20, WTB-16, and WTB-16PD. As a direct OEM replacement, EM491160 is manufactured to the exact thread specification and material grade required by these machines, ensuring a secure, leak-free fit in the original port location. Sourced directly through Multiquip's authorized parts network, this plug delivers the confidence of factory-correct fitment for both mixer and buggie applications. Keep this part number on hand for routine maintenance or fluid system servicing on your PRO or WTB series equipment.
Key Features
- Exact 1" NPT Thread Specification — machined to the National Pipe Taper standard for a pressure-rated, leak-free seal without the need for custom fitting or thread chasing.
- Genuine OEM Construction — manufactured to Multiquip's material and dimensional requirements, so the plug seats correctly and holds under the thermal and pressure cycles typical of mixer and buggie operation.
- Broad Fitment Across Two Equipment Families — compatible with PRO12, PRO12E51, PRO12E53, and PRO20 Essick stationary mixers as well as WTB-16 and WTB-16PD Whiteman track buggies.
- Fluid System Integrity — a properly seated pipe plug prevents fluid loss from unused ports, protecting the surrounding system from contamination and maintaining correct fluid levels during operation.
- Fuel and Fluid System Safety — in fuel and hydraulic circuits, a failed or missing plug can result in leaks that create fire hazard or hydraulic pressure loss; using the correct OEM plug eliminates that risk.
A pipe plug seals off unused or temporary access ports in a fluid system — such as oil, hydraulic, water, or fuel circuits. The 1" NPT taper thread creates a self-tightening mechanical seal as the plug is torqued into the port, preventing fluid from leaking out or contaminants from entering. When a plug is cracked, cross-threaded, or missing entirely, the result is fluid loss, potential system contamination, and on fuel or hydraulic circuits, a serious safety concern that can sideline the machine until the port is properly sealed again.
