Locking Grease Coupler for Mechanics

The Original LockNLube Grease Coupler is designed to end greasing frustration. Its unique features ensure grease goes into the machine, not on it. Locks on, stays on, and is hands-free - no more broken zerks or leaks.

The coupler is compatible with all grease guns and fittings. It features a 1/8" NPT female thread that works with pneumatic, manual, and electric grease guns from any manufacturer. The patented locking technology adapts to all metric and SAE specification zerk fittings.

Rated to an impressive 10,000 PSI (690 Bar), this coupler will not leak or pop off regardless of the grease gun used. Even under high pressure, it easily disconnects with a simple thumb lever, eliminating the need to fight and twist.

Uniquely, the LockNLube Grease Coupler is the only rebuildable option on the market. Each purchase includes a free rebuild kit, allowing the user to replace the durable nitrile rubber seal and four hardened steel jaws. This ensures the lowest lifetime cost and keeps the coupler performing like new.

The sliding sleeve design creates a leak-proof seal when the jaws lock onto the zerk. Grease goes directly into the fitting, not spilling onto the machine. This hands-free operation eliminates messy, wasteful greasing.

For hard to reach fittings, an XL version (GC81042) is available with a 2-inch longer barrel. The 5/8-inch (16mm) diameter front also allows the coupler to fit most recessed grease zerks, about 1mm larger than standard couplers.

Weighing just 4 ounces (100g), the LockNLube Grease Coupler is a compact yet durable solution. Its patented locking mechanism and resilient components are protected by US Patent #8,955,544.

In summary, the LockNLube Grease Coupler is a hands-free, leak-free greasing tool compatible with all equipment. Key features include:

• Locks on, stays on, won't leak up to 10,000 PSI
