LockNLube LNL121 Low Profile Push-On 90° Grease Coupler Adapter

The LockNLube LNL121 is a low-profile, push-on 90° grease coupler adapter built for fittings with minimal overhead clearance. Instead of swapping couplers or carrying a second grease gun, snap your jaw-type coupler—LockNLube® or standard—onto the rear Zerk of the LNL121 and press the open fork over a straight Zerk fitting. The compact body and push-on design make it possible to service fittings tucked beneath guards, housings, or crossmembers where a standard coupler won’t align. A tight sealing face helps keep grease going into the joint, not around it, so cleanup is reduced and flow is predictable.

Sized for daily shop and field work, the LNL121 fits both SAE and metric grease fittings and threads directly where needed using its 1/8″ NPT (male) x 7/16-28 (female) interfaces. Keep one in the cart or service truck to solve low-clearance points on trucks, heavy equipment, farm implements, and plant machinery—without changing hoses, guns, or setup.

Markets

• Fleet & Truck Maintenance Reaches chassis and suspension Zerks hidden by brackets.
• Construction & Heavy Equipment Handles pins and bushings on loaders and excavators with limited access.
• Agriculture Gets to fittings under guards on tractors and implements.
• Industrial & Manufacturing Supports PM on presses, conveyors, and fixtures.

Maintenance crews value adapters that remove delays at a single hard-to-reach fitting. The LNL121 turns any jaw-type coupler into a right-angle, low-profile grease coupler in seconds, so technicians can stay with one grease gun and move through PM lists without reconfiguring tools. The push-on fork stabilizes the connection on the Zerk while the sealing face helps prevent blow-by. Because it fits SAE and metric fittings and offers both 1/8″ NPT (male) and 7/16-28 (female) threads, the adapter works across mixed fleets—from road trucks to compact equipment—keeping service predictable and tidy.

Why Professionals Choose the LockNLube Low Profile Push-On 90° Grease Coupler Adapter

Technicians pick the LNL121 when a standard grease coupler adapter won’t fit. The push-on 90° head slides over a straight Zerk in cramped spaces, creating a secure, leak-resistant seal so grease flows on the first try. Because it connects to any jaw-type coupler, crews keep one grease gun and switch to the adapter only when needed—no hose or coupler changes. The dual-thread design and small form factor make it useful across mixed fleets and equipment lines. For users searching for a low-profile 90 degree grease coupler to handle low-clearance fittings quickly and cleanly, the LNL121 is a simple, reliable solution.
