    "Best grease gun I've owned! Works exactly as described. Zero issues with priming the gun. The locking coupler works fabulously and leaves a free hand to help pump."

    CARE & MAINTENANCE

    Check out our YouTube channel for an easy method to clean dirt and grit out of your coupler. This will extend the life of the seal, which means longer use time between rebuilds. If you find your coupler starting to leak, try this cost-saving tip before you put a rebuild kit in it.
    Consider using a Coupler Cap and Zerk Fitting Caps to keep your equipment clean.
