LockNLube Locking Grease Coupler 1/8" NPT 10,000 PSI | Heavy Duty Universal Grease Gun Tip

• SECURE LOCKING DESIGN: Lock on grease coupler stays attached for leak-free greasing. No need to hold in place, allowing both hands to operate your grease gun with ease and control.
• REBUILDABLE FOR LONG LIFE: The only grease gun coupler with a rebuildable locking mechanism. Reduces replacement costs and extends product lifespan for heavy-duty maintenance tasks.
• UNIVERSAL NPT COMPATIBILITY: Fits all grease guns with 1/8 in NPT threads, including battery, pneumatic, and manual models. Upgrade your grease gun for reliable performance every time.
• FITS ALL GREASE FITTINGS: Works with SAE and metric Zerk fittings. Includes adapters for hard-to-reach spots, making it the best grease gun coupler for versatile equipment maintenance.
• SIMPLE ONE-HAND OPERATION: Press the thumb lever to attach or release the coupler, even under pressure. The locking grease fitting ensures quick, easy, and mess-free greasing every use.

• Attach the Coupler — Align the LockNLube coupler with the Zerk fitting on your equipment. Push the coupler firmly onto the fitting until it clicks or seats securely. The four hardened jaws will engage automatically.
• Operate the Grease Gun — With the coupler locked, use your other hand to operate the grease gun. Pump grease until the desired amount is applied. The secure lock prevents leaks and allows for steady pressure application.
• Release the Coupler — Once greasing is complete, press the thumb lever on the coupler. This retracts the jaws, allowing for quick and easy detachment from the Zerk fitting, even if it's still under pressure.
