A device for preventing leakage and spillage of fluids from a canister type oil filter during removal thereof from an engine block is in the form of an annular elastomeric sleeve having an upper end and a lower end. The upper end has an opening adapted to fit over the exterior of an oil filter. The bottom end of the sleeve has an opening of lesser diameter than that of the upper end and the body of the sleeve adjacent the lower end has smooth contours and is of increased thickness relative to the body of the sleeve. A plurality of protrusions extend inwardly from the inner surface of the shape positioned circumferentially around the shape and are located between the upper and lower ends thereof.
