Multiquip 491008 Grease Fitting Plug

The Multiquip 491008 Grease Fitting Plug is a genuine OEM component designed for a wide range of MQ Mixers, Essick Mixers, Whiteman Mixers, and Multiquip Rollers. As an authentic Multiquip replacement, part 491008 is manufactured to the same standards as the original, ensuring a direct, trouble-free installation in the field. Confirmed fitment includes models across the MC, WM, EM, and AR series, covering concrete mixers, mortar mixers, and asphalt rollers. Sourcing the correct grease fitting plug by part number helps protect lubrication points and extend the service life of critical bearing and pivot assemblies.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original material and thread specifications, ensuring a secure, leak-free seal at every lubrication port.
• Thread-Matched Direct Replacement — Engineered to match the original thread pitch and head profile for straightforward installation without rework or adaptation.
• Broad Cross-Series Fitment — Compatible with MC, WM, EM, and AR series equipment, including concrete mixers, mortar mixers, and asphalt ride-on rollers across the Multiquip portfolio.
• Lubrication Point Protection — Seals grease fittings when not in use, keeping contaminants such as dirt, debris, and moisture out of bearing cavities and pivot points.
• Low-Cost Preventive Maintenance Item — A small but essential part; replacing a missing or damaged plug before grease purges or contamination occurs prevents costly bearing and shaft wear down the line.

A grease fitting plug seals a zerk or grease nipple port when active lubrication is not taking place. Its primary role is to prevent dirt, water, and debris from entering the grease channel and contaminating the bearing or pivot it serves. On equipment like concrete mixers and asphalt rollers — both of which operate in harsh, abrasive environments — an open or damaged fitting port can quickly introduce contaminants that accelerate wear on shafts, bearings, and bushings. When a plug is missing or fails to seat correctly, grease can also purge from the fitting under vibration, leaving the lubrication point dry and the component at risk of premature failure.
