Heavy-duty 4-jaw coupler screws directly into the body of your Original Grease Buster®
⚠️ Important Compatibility Notice: The new black Grease Buster® Coupler Assembly is not compatible with Grease Buster® units manufactured before May 1, 2026. Both the body thread and nipple-to-coupler thread have changed. If your Grease Buster® has a silver coupler, it uses the old thread spec and the new black assembly will not fit.
