WORKPRO 36mm Oil Filter Socket Wrench, 6-Point Hex, 3/8-Inch Drive
Product description
Pros
Choosing an oil filter tool often comes down to whether you need a general-purpose wrench or a socket shaped for a specific filter cap. This WORKPRO 36mm socket is designed for cartridge-style housings, with a six-point profile that grips the cap’s flat sides. Its slim 32mm height is useful when working around filter caps in tight spaces.
The six flat contact surfaces provide a secure fit, while rounded edges are designed to help protect the filter canister from corner damage. Made from heat-treated 40Cr alloy steel with a black powder-coated finish, the socket is built for hands-on filter service. Its 3/8-inch drive connects to a matching ratchet or drive tool, offering a more purpose-built approach than gripping a cap with an adjustable wrench. Buyers also describe it as a solidly built tool that fits their applications, some specifically mention use on Audi S4 filter housings and Mercedes oil changes.

How to use it
Match the 36mm socket to the cartridge-style filter housing on the vehicle, then attach it to a 3/8-inch drive tool. Seat the six-point profile evenly over the cap before turning, so the flat sides engage the socket rather than concentrating contact at the corners. The low-profile body is intended for filter caps with limited surrounding clearance, making it a practical choice for routine oil service in a home garage or workshop.
This socket can also function as a fuel filter socket for some Duramax engines. Vehicle fit depends on the filter housing and application, so use it only where the 36mm size and cartridge-style design match. It is a focused choice for owners or technicians who want a dedicated cap-fitting socket rather than a general wrench for multiple fasteners.
Questions before you buy
What type of filter housing is this designed for? It is made for vehicles equipped with a cartridge-style oil filter housing. The listed applications include some Ford F250 6.0 and 6.4 models and various BMW, Mini, Volvo, Audi, VW, and Porsche vehicles.
What drive tool does it use? The socket has a 3/8-inch drive, so pair it with a compatible 3/8-inch ratchet or drive tool.
Can it be used on a fuel filter? It can also serve as a fuel filter socket on some Duramax engines. Check that the application uses a matching 36mm filter cap before use.
Final verdict
For cartridge-filter service, the WORKPRO 36mm socket combines a close-fitting six-point design, a compact 32mm height, and a 3/8-inch drive in one dedicated tool. It makes sense if you work on a listed compatible vehicle and want a socket shaped to engage the filter cap’s flat sides, especially where access around the housing is tight.
