6 reasons why people are switching to the LockNLube® Grease Coupler 🎉

Here are the top six reasons why everyone is ditching their old-style grease coupler for the mess-ending, grease saving, frustration-free, LockNLube® Grease Coupler.

1. Locks on and stays on—like having an extra hand!

No need to hold the coupler in place while trying to grease. The LockNLube® Grease Coupler locks on tight and lets you use both hands on the grease gun.

2. Rated up to 10,000 PSI

Today’s high-powered cordless battery grease guns put out more pressure than ever before. Traditional couplers simply can’t take the power!

3. Easily disconnects, even under pressure!

No more broken Zerks from wrenching an old coupler off a stuck fitting. A simple press of the thumb lever opens the LockNLube’s patented jaws to easily release from the Zerk. It’s especially useful on recessed Zerks!

4. 1/8" NPT compatible with all grease guns!

Whether you are using Grandpa’s old Alemite lever grease gun, or the latest battery or pneumatic grease guns, the LockNLube® Grease Coupler can be added to upgrade your grease gun.

5. No mess!

Using the LockNLube® Grease Coupler means that grease goes IN not ON the machine!

6. The Only Rebuildable Grease Coupler

The LockNLube® is the world's only rebuildable grease coupler—lowest lifetime cost! The body of the tool is warrantied for life. If it ever starts leaking, you can rebuild it cheaply and easily.
