The Lisle 3-Jaw Filter Wrenches and Adapters, Nos. 63830 and 63850, are designed with gripping jaws to grab even stubborn filters. The 63830 covers the most common filter sizes, and the 63850 works on smaller filters. The removable adapter provides lower clearance in tight spots, the company says. These tools can be used with a 3/8" or 1/2" square drive, as well as be used with a 21mm wrench or socket. The 63830 has a range of 58 to 110mm, and the 63850 has a range of 61 to 124mm.
