LockNLube LNL120 90° Grease Coupler Adapter with Hardened Steel Jaws

The LockNLube LNL120 is a 90-degree grease coupler adapter designed to reach fittings a straight coupler can’t. Slip your grease coupler (LockNLube® or any standard coupler) onto the Zerk under the LNL120’s collar and you can service fittings tucked behind guards, yokes, and linkages without changing guns or hoses. Three hardened steel jaws, a rubber seal, and an internal check valve create a tight, reliable connection that helps grease go into the fitting— not around it. The compact head and protective spring neck help with alignment while keeping the adapter steady in cramped spaces.

Built for daily maintenance on trucks, construction equipment, farm implements, and plant machinery, this 90° adapter gives technicians a straightforward way to handle awkward fittings. Keep one in the service truck or on the shop cart to solve clearance issues fast and keep PM routes moving.
