The Multiquip 491701 Grease Fitting is a genuine OEM component designed for a broad range of Multiquip ride-on rollers and hydraulic concrete pumps, including AR13D, AR13H, AR13HAR, AR13HA, AR14H, LS-40, LS40D, LS40TD, LS50TD, LS60TD, LS300, LS300G, LS300GK, LS300P, LS400, LS450, LS500, LS600, and LS600P series equipment. Sourced directly from Multiquip, this fitting meets the same specifications as the original hardware installed at the factory. DHS Equipment supplies this part to keep your equipment properly lubricated and protected against premature wear.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and thread specification of the original fitting, ensuring proper grease flow and seal integrity at every lubrication point.
- Direct-Thread Installation — Engineered to thread directly into existing ports with no reworking of fittings or housing required, making field replacement fast and straightforward.
- Broad Fitment Coverage — Compatible with AR13D, AR13H, AR14H ride-on rollers and the full LS-series hydraulic concrete pump lineup, including LS300, LS400, LS500, and LS600 models.
- Protects Critical Bearing and Pivot Points — A functional grease fitting allows lubricant to reach internal bearings, pins, and pivot assemblies; a blocked or damaged fitting starves these surfaces and accelerates wear.
- Corrosion-Resistant Design — Built to withstand the moisture, concrete slurry, and compaction debris common to roller and pump jobsite environments, maintaining a reliable seal over extended service intervals.
A grease fitting — sometimes called a zerk fitting — is a small but essential lubrication access point threaded into bearings, pins, pivot points, and other moving components throughout the machine. When you press a grease gun against the fitting, it opens a spring-loaded check valve that allows fresh grease in while preventing dirt and moisture from entering when the gun is removed. A missing, clogged, or damaged fitting cuts off that lubrication pathway entirely, leaving metal-on-metal contact that causes rapid wear, overheating, and eventual component failure. Replacing a failed fitting promptly with the correct OEM part restores full lubrication access and protects the surrounding components from costly damage.
