【3-in-1 Universal Design】 One tool removes 1/4", 5/16" (6mm, 8mm) push-to-connect fittings—the mainstream sizes for copper, PEX, and CPVC pipes. Compatible with multiple brands of quick-connect fittings, this versatile assistant handles all your plumbing repair needs, especially in tight spaces. 【Slim Jaws for Confined Spaces】 Innovative slim jaw design easily reaches deep into densely packed fittings or narrow equipment interiors, precisely releasing quick-connect rings. Effectively prevents hose deformation and damage caused by manual forceful pulling. 【One-Handed Working, Effortless & Efficient】 Ergonomic design enables easy single-handed operation: simply clamp the tubing and press the lever with your thumb—the built-in spring bar automatically ejects the fitting. The entire process is fast, labor-saving, and safe. 【High-Strength Durability with Comfortable Grip】 Core components made of heat-treated carbon steel deliver high strength and long-lasting durability. Handles wrapped in PP and TPR soft materials provide comfortable grip, effective slip resistance, and reduced hand fatigue during extended use. 【Compact & Portable, Easy Storage】 Small and lightweight with a practical tool lock design for secure, space-saving storage. The ideal choice for home toolboxes and professional repair kits.
