Designed for contractors who repair or install PEX plumbing systems, the low-profile, lightweight Ridgid PEX-One (54253) presses multiple-size connections, up to one inch, with a single tool. It gives you the one-handed functionality you need for easy and accurate press connections in tight or hard-to-reach spaces. The PEX-One presses 1/2", 3/4 and 1" fittings. It even includes a fastening hand strap which makes working overhead much easier.
