The PEX GUN is the world's leading PEX and PEX-AL Pipe installation tool. Just pull the trigger and the PEX GUN ties pipe to wire mesh or rebar in one second and is 5 x's faster than manual tying. This simple operation reduces potential wrist damage such as carpal tunnel injuries. Using the optional extension bar reduces the risk of back injuries. At less than $0.05 per tie, the PEX GUN pays for itself only after a few uses.
