Lisle Oil Filter Pliers 50750

Adjustable jaws and sturdy construction make these a practical choice for gripping and removing stubborn spin-on oil filters.

Not for: Cartridge filter housings or filters with very limited surrounding clearance.

Claude also picks Lisle for “cramped filter access”.

Which one fits you

cramped filter access

Lisle (brand)

Lisle makes swivel-jaw filter pliers and wrenches that turn filters in tight engine bays where a straight plier can't swing.

Not for: Anyone who only services filters with open access and wants the simplest tool.

one plier for filters and general shop use

Knipex Cobra (line)

Cobra self-locking water pump pliers adjust finely and grip round parts hard, so they cover filters as well as everyday plumbing and automotive jobs.

Not for: Anyone who wants the deep curved jaws of a dedicated filter plier for large-diameter filters.

Check before you buy

Jaw capacity range. The plier's adjustable jaw range must span the outside diameter of your filter canister. A plier that can't open wide enough or close tight enough on your filter simply can't grip it.Advertised: 1-3/4 to 3 in (Channellock)
Filter type. Pliers only work on spin-on canister filters; cartridge housings need a cap-specific socket wrench. Gripping a plastic cartridge housing cap with pliers can crack it.
Jaw shape and teeth. Look for curved, serrated jaws that wrap the canister rather than flat jaws. Curved jaws spread force around the can and bite through oil, while flat jaws slip and crush.
Access and swing room. Check the clearance around your filter; choose swivel jaws or a cap or band wrench if there is little room. Fixed pliers need room to rotate the handles, and many modern engine bays don't allow it.
Handle length. Longer handles give more leverage on over-tightened filters but need more room to swing. Stuck filters are the main reason to buy pliers rather than a cap wrench.

Questions

Pliers, band wrench or cap wrench?

Cap wrenches fit one filter size and work in tight spaces. Band wrenches suit mid-range access. Pliers grip the widest range of sizes and beat stuck filters, but need swing room.

Is it OK that the pliers dent the old filter?

Yes. The old filter is discarded, but grip near the base so you don't puncture the can and spill oil.
