The GC82023 Special Edition Black & Gold Lock-N-Lube® Grease Coupler is the original locking grease coupler designed to finally end greasing frustration. It locks on, stays on, and won’t leak, even under extreme pressure—rated up to 10,000 PSI. It also disconnects easily under pressure, helping prevent damaged or broken Zerks. Compatible with all grease guns (battery, pneumatic, or manual) via 1/8″ NPT, it works on SAE and metric Zerk fittings alike. Best of all, it’s fully rebuildable and includes a rebuild kit, keeping lifetime costs low while keeping grease where it belongs: in the machine, not on you.
