Sierra Oil Filter Wrench 18-9778, Fits 2-7/16 Inch to 3 Inch Small Outboard Filters

The Sierra Oil Filter Wrench 18-9778 is a precision formed metal tool built to remove and install screw-on type canister oil and fuel filters on small outboard engines. The band-style design wraps around the filter housing and pivots into place, letting you break a stuck filter loose without crushing or puncturing the canister the way a strap wrench can. Its tempered metal band is sized for filters measuring 2-7/16 inches through 3 inches in diameter, matching the compact filter housings used on small outboard motors.

Construction is alloy steel with a powder coated black finish for corrosion resistance in a marine environment, and the pivoting handle gives extra leverage in tight engine compartments where clearance around the filter is limited. Because it uses a mechanical band-and-handle action rather than a socket, it works even when a filter has been overtightened or has started to corrode to its mounting surface. This wrench is sold on its own as a standalone tool for routine oil and fuel filter service.
