Check Before Ordering

Make Sure It Fits Your Grease Gun and Fitting

Most failed purchases happen because the thread or fitting size was never checked.

✅ Grease gun connection

Designed for grease guns using a standard 1/8-inch NPT threaded connection.

✅ Compatible grease fitting size

The supplied product image indicates compatibility with fittings measuring up to 14 mm.

⚠️ Verify before purchase

Measure your thread and grease fitting. Do not assume every grease gun or fitting uses the same dimensions.

Less Mess. Fewer Restarts.

Loose Couplers Turn a Simple Grease Job into a Frustrating One

When a standard coupler slips off under pressure, grease can leak around the fitting and force you to stop, reconnect and try again.

✅ Helps reduce unwanted disconnection
✅ Helps minimize grease leakage around compatible fittings
✅ Keeps one hand available to control the grease gun
✅ Releases without prying or pulling against the fitting

Built for Practical Maintenance

The Locking Upgrade Your Grease Gun Was Missing

Each part is designed around a more stable connection and easier release during routine equipment servicing.

🔒 Six Jaws Surround the Fitting

The synchronized six-jaw head grips around a compatible grease fitting instead of relying on a loose push-on connection.

✅ More stable connection during greasing
✅ Thickened internal spring supports locking force
✅ 1/8-inch NPT threaded connection

Frequently Asked Questions

Will it fit every grease gun?

No. It is designed for a 1/8-inch NPT connection and works with many manual, pneumatic and electric grease guns. Confirm your grease gun thread before ordering.

What size grease fittings can it grip?

The supplied product image indicates compatibility with grease fittings measuring up to 14 mm. Measure your fitting before purchase.

What is the maximum working pressure?

The supplied product image states a maximum working pressure of 10,000 PSI. Never exceed the pressure rating of the lowest-rated component in your system.

Does it completely prevent grease leaks?

The six-jaw design is intended to create a tighter connection and help reduce leaking. Results still depend on correct sizing, attachment and the condition of the grease fitting.

How do I release it after greasing?

Squeeze the double handles to open the locking jaws, then lift the coupler away from the fitting. Do not pry or force it sideways.
