The Deluxe MP 5/16" tubing tool is a maple producer’s all-in-one solution for tubing installation and repair. It features a retractable safety knife, a retractable tube spreader for easier fitting insertion, and a self-calibrating jaw pressure system that ensures constant clamping force (adjustable if needed). Equipped with two integrated Vise-Grip 5WR pliers with 5/16" jaws, it handles most fittings with precision and reliability. Built from durable steel with polyethylene-coated handles for comfort and grip, it is safe, simple, and practical. A premium tool that has been the hallmark of the Deluxe line since 1980.
