LockNLube Grease Coupler (Standard 1/8″) – (GC81011-NPT/GC81068-NPT) / (GC81011-BSPT/GC81068-BSPT)

The original, patented LockNLube® Grease Coupler, a quick-connect grease gun coupler that locks onto grease fittings (zerks) and stays on without leaking up to 10,000 PSI. With a thumb lever, it releases instantly even under pressure, ending the common frustrations of greasing (couplers popping off, messy spurts, stuck couplers). Fits all standard grease guns via 1/8″ connection and is fully rebuildable.
