The Jonnesway spider-type oil filter wrench (Universal up to 120 mm) is an ingenious tool designed to automatically adapt to a vast variety of filter sizes, eliminating the need for multiple fixed cup wrenches. Its gear mechanism operates three grooved steel claws that close concentrically when turned: the more force applied to the ratchet, the stronger the claws bite into the filter body, ensuring a non-slip grip.
Designed to be operated with a breaker bar or ratchet (typically 1/2" or 3/8" with an adapter), this tool is the ultimate solution for filters located in remote or recessed areas where there is no lateral space to move the handle of a strap or plier wrench. Its compact and robust construction makes it a favorite for oil changes in modern vehicles with dense engine compartments.
