LockNLube LNL143 72PC Complete Grease Fitting Replacement Kit

The LockNLube LNL143 is a jobsite-ready assortment of the most common SAE and metric Zerk fittings, plus the tools needed to remove broken fittings and retap stripped holes. Packed in a bright, compartmented case that’s easy to spot in a service truck or shop drawer, the kit lets technicians replace clogged or damaged fittings on the spot and restore grease flow without a second trip to the parts counter. You get straight fittings in four thread sizes, 90° SAE fittings for tight clearances, two “easy-out” multi-tools sized for 1/4″-28 and 1/8″-27 work, and 20 tethered caps (yellow and red) to keep new fittings clean between PMs.

Whether you maintain trucks, heavy equipment, or farm implements, this grease fitting kit keeps common sizes organized and within reach. The included tools install and extract Zerks cleanly and can rethread damaged ports to standard pitches, saving time compared with teardown or component replacement. For shop maintenance routes or field service calls, the LNL143 provides a practical, all-in-one way to keep lubrication points serviceable and machines working.

With 20 protective caps included, the fresh fittings stay clean and ready for a grease gun. The labeled case rides well in a truck box, making it simple to carry the right parts to every machine on the route.
