LockNLube GC81011 Grease Gun Coupler

The LockNLube GC81011 Grease Gun Coupler offers a reliable solution for leak-free greasing. Compatible with all grease guns and fittings, it securely locks in place and stays attached, even under pressure, minimizing mess and grease waste. Featuring a unique sliding sleeve and thumb lever, the LockNLube Grease Coupler firmly locks its four steel jaws onto the Zerk fitting, ensuring a tight, leak-proof seal. When finished, a simple press of the thumb lever releases the coupler, even under pressure. This design is especially effective for greasing recessed fittings, making coupler removal hassle-free.
