WORKPRO Adjustable Oil Filter Wrench 2-3/8–3-1/8" Auto-Clamp with 1/2" Drive Compatibility, Heavy-Duty Grip

WORKPRO Universal Oil Filter Wrench is an adjustable auto-clamp removal tool that fits 2-3/8" to 3-1/8" (60–80 mm) oil filters and drives with a 1/2" square or 7/8" wrench for fast, secure removal.

This compact, heavy-duty wrench is built to tackle stubborn engine oil filters and hard-to-reach fittings. Its spring-assisted auto-clamp and multi-tooth gripping head create a firm hold while drop-forged steel construction delivers the torque needed for stubborn filters. The design balances hand comfort, environmental compliance, and workshop durability for routine oil changes and mechanical maintenance tasks.

How does the auto-clamp system make filter removal easier?

The integrated spring automatically tightens the gripping head around the filter as you pull upward, reducing the need for manual adjustments. That means fewer slips and quicker engagement in tight engine bays.

• Spring-assisted auto-clamp for fast engagement
• Self-adjusts to filter diameters from 60 to 80 mm
• Reduces time spent repositioning when working in confined spaces

Will this wrench fit my oil filter and workshop tools?

Yes — the head spans 2-3/8" to 3-1/8" (60–80 mm) so it covers most common spin-on filters. It accepts a 1/2" square drive or a 7/8" wrench/socket, making it compatible with standard ratchets and hand tools.

• Fits common engine filter sizes (60–80 mm)
• Use with 1/2" drive ratchets or 7/8" sockets
• Works on filters, conduit fittings, and similar cylindrical parts

How durable and reliable is the construction?

The wrench uses drop-forged steel and a multi-tooth grip pattern to resist slipping and withstand repeated torque. Materials and finish are chosen for workshop use, while manufacturing standards from a recognized global tools supplier ensure consistent performance.

• Drop-forged steel body for high torque resistance
• Multi-tooth contact surface for a secure grip
• Engineered for repeated use in automotive and maintenance settings

Is the wrench comfortable and environmentally considerate?

Ergonomic shaping reduces hand fatigue during manual operation, and the body is designed to be hand-friendly for quick changes. Materials meet environmental thresholds, with low o-phenol content to align with safer manufacturing practices.

• Ergonomic profile for better hand contact and control
• Low three-o-phenol total content (<1000 ppm)
• Compact size for easier storage and transport

Who this is for: This WORKPRO wrench is ideal for DIY mechanics, professional technicians, and fleet maintenance teams who need a compact, reliable tool for oil filter removal and small-diameter fittings. If you perform routine oil changes, work in tight engine compartments, or require a versatile tool that pairs with standard 1/2" drive gear, this adjustable, spring-assisted filter wrench is built to make the job faster and less frustrating.
