The Sealey AK641 Oil Filter Chain Wrench is designed for automotive technicians and DIY enthusiasts who require a heavy-duty solution for removing stubborn or inaccessible oil filters. Its primary benefit is the combination of high-torque leverage via a square drive and a flexible chain mechanism that securely grips filters of varying sizes. While this tool offers exceptional grip, users should be cautious not to overtighten the chain during installation to prevent crushing or damaging the filter casing.

It is generally recommended to hand-tighten oil filters to avoid damage. Use this tool primarily for removal.
The wrench features a satin finish that resists corrosion, but you should still wipe it clean of oil and debris after use to prolong its lifespan.
While it accommodates up to 135mm, it can secure smaller filters, though you must ensure the chain has enough slack to wrap around the diameter effectively.
Yes, the head is designed to be turned by either a 1/2" square drive tool or a 20mm spanner.
If the oil filter is within the 135mm capacity and the space allows for the chain link to wrap around, it will work; however, it is primarily designed for automotive/van filters.
Ensure the filter surface is wiped clean of excess oil and that the chain links are seated firmly in the tool's locking teeth.
Reverse the direction of the handle to release tension on the chain, then gently wiggle the tool to disengage the hook from the casing.
Setup requires no assembly; the tool is ready to use out of the box. Ensure you are using a high-quality 1/2" ratchet or a properly sized 20mm spanner to avoid rounding off the wrench's integrated nut.
