The Powerbuilt Self Adjusting Oil Filter Pliers automatically adjust to the size of the filter to be removed. These pliers allow for single-hand operation, performing three times faster than conventional filter pliers, according to the company. The uniquely designed mechanisms tighten as users turn the tool – the more users turn, the tighter the pliers grip. It is self-adjusting, simple to use and breaks loose stubborn oil filters with ease. The no-slip grip and padded dipped handles provide comfort so users can easily hold the tool. The opening size fits all filters, from 2-1/4” to 4-3/4”, conforming to any style of filter. Layered steel construction and serrated jaws provide greater durability and a tighter gripping force.
