Multiquip 2621 Grease Zerk

The Multiquip 2621 Grease Zerk is a genuine OEM grease fitting designed for a wide range of Multiquip and Whiteman equipment, including ride-on roller screeds, vibratory screeds, hydraulic and hydrostatic ride-on power trowels, masonry saws, and concrete vibrators. As a direct OEM replacement, the 2621 is manufactured to the same specifications as the original hardware, ensuring a proper thread engagement and seal at every lubrication point. Compatible models span the WRS, STX, HTX, HTN, HHN, MD, JWN, SP, and MP series, making this a versatile service item to keep on hand across a mixed Multiquip fleet. Sourced directly through DHS Equipment, this is the exact part called out in Multiquip service documentation.

Key Features

• Genuine OEM Thread Spec — Manufactured to the exact thread pitch and head profile specified by Multiquip, ensuring full grease-gun engagement without cross-threading or leakage.
• Drop-In Service Replacement — Threads directly into existing grease ports on supported equipment with no rework or re-tapping required on properly maintained fittings.
• Broad Fleet Coverage — Fits WRS roller screeds, STX, HTX, HTN, and HHN ride-on trowels, MD hydraulic trowels, MP masonry saws, SP flat saws, and vibratory screed models — one part number covers a wide range of machines.
• Keeps Lubrication Paths Open — A properly seated zerk allows grease to flow freely into bearings, pivot points, and shafts. A damaged or missing fitting blocks lubrication entirely, accelerating wear on critical moving components.
• Corrosion-Resistant Ball Check — The internal ball-and-spring check valve seals the fitting between grease intervals, keeping contaminants, water, and debris out of the lubrication point.

A grease zerk — also called a grease nipple or grease fitting — is a small but critical hardware component threaded into lubrication ports on machinery. When a grease gun is pressed against the fitting, the internal ball check valve opens under pressure, allowing fresh grease to enter the bearing or joint. Once the grease gun is removed, the ball reseats and seals the port, preventing contamination from entering. When a zerk is damaged, stripped, or missing, grease cannot be delivered to the component it serves, starving bearings, spindles, and pivot assemblies of lubrication and causing premature wear or failure. Replacing a damaged fitting promptly is one of the lowest-cost, highest-impact maintenance steps on any piece of concrete finishing or screed equipment.
