The top 3 Lock on Grease Couplers
The coupling between the tip of the gun and the feedline is a critical part of your set up. If you have a tool that operates at 12,000-psi and you link it to a lock-on coupler that can only handle 10,000-psi, you’re asking for an accident to occur in your workshop.
How Does a Lock-On Grease Coupler Work?
The fitting is leak-proof, featuring silicon seals to prevent any backflow from the grease line. The locking head will grip the grease fitting, and you can release it by pressing the thumb lever.
How Do I Select the Right Lock-on Grease Coupler?
Look for a lock-on grease coupler that works on all fittings, including SAE and metric. Your lock-on grease coupler must be compatible with all leading brands, including Allstar, Alemite, Lumax, Grainger, Plews lubrication, SKF, Macnaught, Milwaukee, John Deere, Legacy, Sealey, and many others.
