LOCK N LUBE GREASE COUPLER

The Lock N Lube Grease Gun Coupler is compatible with all grease guns and grease fittings. It is equipped with a sliding sleeve that is activated by a thumb lever. The sleeve locks the four spring-steel jaws onto the Zerk fitting, and releases the jaws by pushing on the thumb lever. When the jaws are locked onto the Zerk, a leak-proof seal is created. The locked connection is positive and rigid preventing the coupler from coming loose and breaking the leak-proof seal.
