LockNLube Grease Coupler

The LockNLube coupler has a unique sliding sleeve activated by a thumb lever. The sleeve either locks the four spring-steel jaws onto the Zerk fitting or releases the jaws from the Zerk. When the jaws are locked onto the Zerk, a leak-proof seal is created. No hands are needed to align or hold the coupler in place while greasing.

The LockNLube is not a disposable throwaway. A spare seal kit is included with each coupler. Fits electric, pneumatic and manual grease guns with 1/8 NPT hose connection.
