The OTC 6720 Flare Nut Pliers are designed for use on new or damaged flare nuts that have been rounded or rusty. The pliers fit standard or metric nuts and bolts and range in adjustment size from 1/4’’ or 6mm to 5/8’’ or 16mm. The angled jaw allows for clearance around frames and bulkheads, making it an ideal tool for brake or hydraulic lines. With more grip, the Flare Nut Pliers provide more support than a standard open-ended flare nut tool and prevents stripping for an overall easier job.
