Grease Buster® Hose Extension

The 5" Hose Extension replaces the installed Grease Buster® coupler to make it easier to reach clogged fittings in tight spaces. Includes a heavy-duty 4-jaw coupler to attach securely to your Zerks.

Note: the color of the hose ends may vary.

⚠️ Important Compatibility Notice: The GB19 Hose Extension is compatible only with Grease Buster® units manufactured before May 1, 2026. If your Grease Buster® has a silver coupler, the GB19 will fit. If you have the new black coupler assembly, the GB19 is not compatible.
