The RIDGID RP 251 is a compact, high-performance in-line press tool designed for professional plumbing, heating and mechanical installation work. Engineered for maximum control in confined spaces, the RP 251 combines a lightweight aluminum body, pistol-grip ergonomics and a powerful 12V brushless motor to deliver consistent, secure press connections every time.

With M-profile jaws (15mm, 22mm and 28mm) included as standard, plus two RIDGID 12V lithium-ion batteries and a fast charger, this kit provides everything required for daily press-fit work on copper and stainless steel systems. The tool delivers up to 140 presses per full charge, supported by an integrated LED work light for improved visibility in dark or obstructed areas.

Supplied in a durable RIDGID hard case, the RP 251 is built for tough jobsite conditions and is drop-tested for long-lasting reliability.
