Designed to work with standard 1\/8\" NPT grease guns — manual, pneumatic, mini and electric — it reaches recessed Zerks and tight spaces where bulkier couplers fail. The kit also includes a compact fittings cleaner to clear residual grease before coupling for a snug, reliable seal.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 6-jaw lock make greasing easier and cleaner?\u003c\/h3\u003e\n\u003cp\u003eThe 6-jaw lock centers and grips the Zerk fitting from multiple angles, preventing side play and accidental pops during pressurization.
