Dual purpose tool for depth and outer diameter measurement and a disassembly aid for pipe fittings, making plumbing tasks efficient and straightforward. Comprehensive measurement with six sizes (1/4 in, 3/8 in, 1/2 in, 5/8 in, 3/4 in, 1 in); accurately measures insertion depth and outer diameter of pipes for precise fittings every time. Laborsaving design: simply insert the pipe into the measurement hole for quick readings; disassemble fittings effortlessly by placing the pipe into the measuring hole for easy removal without extra tools. Practical tool kit: copper pipe deburring depth tool compatible with copper, PEX, CPVC, and PERT pipes; an essential addition to any home or workshop toolkit. Use scenarios: Before connecting fittings on a copper or plastic piping project, verify insertion depth and pipe diameter to choose the correct size. In confined spaces, use the measuring hole as a removal aid to disassemble stubborn fittings without tools. After cutting pipe ends, deburr and check the insertion depth to ensure a clean, snug fit.
