RIDGID ProPress tools — the RP series press tools, jaws, and rings used for cold-press joining of copper, stainless, carbon steel, and PEX without solder, flame, or threading.
RIDGID ProPress is the system most commercial mechanical contractors specify for press-fit copper and stainless. The RP 350 and RP 351 cover 1/2" through 4" copper with a single tool, and Bluetooth diagnostics on the newer models verify cycle counts for warranty work. Beyond the tool itself, the depth of the jaw and ring inventory is what makes RIDGID the default — every fitting size has an authorized jaw.
