This is hands down the best grease gun accessory for faster and easier servicing of grease points. It locks on and won't pop off, even at 10,000 PSI.
Ball joints in particular can require a large amount of pressure to properly inject with grease. Adding this to your grease gun makes the job easy. We've been heavily using ours for many years and are still on the original seals.
*Note that this grease coupler is already included with the Heavy Duty Lever Grease Gun.
Fits 1/8" NPT hose connections (compatible with all grease guns)
Hardened steel jaws grip onto the fitting allowing for one-handed gun operation
Textured thumb lever for improved grip
The world's only rebuildable coupler. Free spare seal kit and jaws included!
