Best Grease Gun Coupler: Lube Shuttle® safeLOCK L Long Reach Grease Coupler

When it comes to couplers, the best grease gun coupler is going to be long enough for the job and durable. You also need a locking grease coupler that will stay locked while you do a task with your hands-free grease gun! Lube Shuttle® has created the best of both worlds in their new safeLOCK Long Reach locking grease coupler. It unlocks under pressures as high as 600 Bar! (over 8,000 psi) so there's no chance of using too much force and breaking it. A full 3.25 inches of reach with a hardened 4 Jaw Locking Coupler makes this an excellent choice for any type of work on vehicles or machinery where reaching into tight spaces is required. And finally, an Integrated Rear Swivel allows you to get into those hard-to-reach areas without having to move your vehicle. When choosing a grease gun coupler, remember the true-lock system will help prevent accidental uncoupling under extreme pressure and temperature conditions, making this a safer option than your standard locking grease gun couplers!
