LockNLube LNL129 Simple 90° Grease Coupler Adapter

The LockNLube LNL129 is a compact right-angle adapter that lets a standard grease gun reach fittings tucked behind brackets, guards, and crossmembers. Snap your jaw-type coupler—LockNLube® or traditional—onto the rear Zerk of this adapter and service 90° Zerk fittings without changing guns or hoses. The slim nose and narrow body help in tight quarters, while the precision coupler head provides a steady seal so grease goes into the joint, not around it. Keep one on the cart or in the truck for those few fittings that stall an entire PM round.
