The 1/2" and 3/4" Push 'N' Connect Depth Gauge and Deburr Tool is a tool designed for use with copper, PEX, or CPVC pipe. The tool will accurately mark depth and deburr pipe to ensure proper installation when using Push 'N' Connect fittings. Insert pipe into appropriate slot for either 1/2" or 3/4" pipe and rotate the tool to deburr the pipe. You can then mark a ring around the pipe to indicate proper depth for Push 'N' Connect fittings to ensure a perfect seal.
