Product Overview

The LockNLube Grease Coupler XL delivers the same locking performance as the original coupler with extended reach for recessed and hard-to-access fittings. Rated to 10,000 PSI, it locks on securely and will not pop off under pressure, enabling true hands-free greasing while reducing mess and frustration. The thumb-activated release allows safe disconnect even at high pressure without damaging Zerks. Its extended length makes it ideal for shielded PTO shafts, axles, U-joints, harvester heads, and other tight access points. It fits all standard grease guns using a 1/8 in. NPT connection and works on both SAE and metric fittings. The rebuildable design allows replacement of jaws and seals instead of the entire coupler, helping reduce long-term operating cost.
  • Locks on, stays on, won't leak, rated to 10,000 PSI - patented locking jaws grip the zerk to create a secure, leak-free seal that will not pop off under pressure, enabling true hands-free greasing and cleaner lubrication
  • Easy release, even under pressure, no broken zerks - thumb-activated sleeve locks and unlocks quickly with one hand, disconnecting safely without pulling, fighting, or damaging grease fittings
  • Universal 1/8 in. NPT compatibility - fits all standard grease guns including battery, pneumatic, and manual models, making it an easy, reliable upgrade for any grease gun
  • Grease goes in, not on, the machine - internal seal directs grease into the bearing instead of leaking around the fitting, reducing mess, waste, and cleanup while improving lubrication
  • Works on all zerk fittings, SAE and metric - designed for universal fit across standard grease fittings for dependable performance on automotive, agricultural, and industrial equipment
  • Rebuildable design, lowest lifetime cost - the only fully rebuildable grease coupler, available with or without a rebuild kit, extending service life and reducing replacement cost in demanding use
