Firstools Adjustable Oil Filter Wrench Set, 2nd‑Gen 12" Long‑Handle with 10‑Position Jaws — 30–138mm Capacity, Non‑Slip Grips

Firstools 2nd-Gen adjustable oil filter wrench set is a two-piece removal tool kit with a 12" long-handle, 10-position quick-adjust jaws, and a 1-1/4" to 5-2/5" capacity for stubborn filters and round engine parts.

This updated Firstools set combines a compact 10" standard wrench and a longer 12" adjustable pliers-style wrench so you can tackle oil filters, pipes, fittings and other round components in tight engine bays or workshop spaces. Built from high-carbon 55 steel with serrated gripping surfaces and soft non-slip handles, the set is designed to increase leverage and control when loosening over-tightened or slippery parts.

How does the 10-position adjustment make filter removal easier?

The wrench’s 10-step quick-adjust mechanism lets you set jaw width precisely without constant readjusting, so you spend less time fiddling and more time turning. A self-locking pivot holds the selected size under load to prevent slippage while you work.

• Ten discrete jaw settings for repeatable widths
• Self-locking pivot keeps jaws steady under torque
• Fast size changes with a single-handed motion

Will this fit the variety of filters and pipes I encounter?

The jaws open from 1-1/4" (30 mm) up to 5-2/5" (138 mm), covering common automobile, motorcycle, ATV and small-engine oil filters as well as many plumbing and conduit fittings. The serrated teeth grip smooth and greasy surfaces to improve contact on round parts.

• 30 mm–138 mm capacity for broad compatibility
• Serrated jaw faces for strong hold on slippery components
• Useful for cars, trucks, lawn equipment and general repairs

What advantage does the 12" handle provide over shorter wrenches?

The 12-inch length increases leverage and reach so you can break loose tight filters in constrained engine compartments with less effort. Soft, textured grips reduce hand fatigue and help maintain control when surfaces are oily.

• Longer handle for better torque and reach
• Non-slip grips for comfort and stability during use
• Improved access in crowded engine bays or tight spaces

What materials and extra features should I expect from this set?

Firstools builds the tools from high-carbon 55 steel for strength and durability under regular workshop use. The set includes a standard 10-inch wrench plus the upgraded 12-inch adjustable pliers, and a few practical additions to increase usability around the garage.

• Constructed from 55 model high-carbon steel for toughness
• Two-piece kit covers multiple jobs without extra tools
• Hidden bottle-opener feature and ongoing product updates
