Alemite B322610 Grease Gun Loader Fitting

Alemite B322610 Loader Fitting is a heavyweight, two‑piece loader accessory for grease guns, engineered to enable loading heavy lubricants from loader pumps. It replaces the standard fill plug in the grease gun head by threading into the gun’s 1/8" NPTF port, allowing direct loading from a loader pump. This loader fitting features a large ball‑check passage and, as a two‑piece design, it is intended specifically for heavy lubricants rather than light or medium grades. The product is documented as a loader fitting for heavyweight lubricants (B322610) and is designed to mate with loader couplers in Alemite’s loader fittings ecosystem; installation is performed by removing the gun head plug and installing the loader fitting. Compatibility centers on grease guns with a 1/8" NPTF port in the head, and the part is commonly discussed alongside loader couplers such as Alemite 306741, which is designed to work with loader fittings B306740 and B322610.
