RIDGID MegaPress Jaws and Rings (Kit 48553)

Description The RIDGID MegaPress Jaws and Rings (Kit 48553) press 1/2″ to 2″ carbon steel pipe without a torch. Built for Viega MegaPress fittings and RIDGID Standard Series press tools, this kit joins Schedule 5 to 40 steel pipe on wet or dry systems. No hot work permit required. Also called Mega Press jaws by many contractors, this kit removes the flame from steel pipe work entirely. That matters most in occupied buildings: hospitals, schools, data centers, multi-family properties where a hot work permit can stall a job for days. RIDGID MegaPress Jaws: What’s in Kit 48553 Kit 48553 includes RIDGID MegaPress jaws and rings sized for the full 1/2″ to 2″ range. Each jaw and ring engages the MegaPress fitting profile and applies even, 360-degree compression around the joint. The result is a permanent, code-compliant seal, no threading, no welding, no drain-down. A typical retrofit or repair on an occupied floor runs like this: isolate the section if needed (not always required with wet-system pressing), prep the pipe end, seat the fitting, and press. Each connection takes under 30 seconds with the correct RIDGID press tool. There’s no cooldown period before the line goes back into service, and no flux or solder residue to clean up afterward. Compatible Press Tools for RIDGID MegaPress Jaws RIDGID CT-400 RIDGID 320-E RIDGID RP 330-B RIDGID RP 330-C RIDGID RP 340 RIDGID RP 350 Any RIDGID Standard Series press tool on this list will run Kit 48553 without an adapter. If you’re building out a crew’s toolkit from scratch, the RP 350 is worth a look, it’s compatible with the full Standard Series lineup beyond just MegaPress. Why Wet-System Pressing Matters MegaPress connections can be made on live systems. That means a leak repair or tie-in finishes without draining the building’s water first, cutting hours off a job that would otherwise require a full system shutdown. On a multi-unit property, that can be the difference between a two-hour service call and a half-day outage notice to every tenant on the riser. The flameless design also matters for insurance and site access. Facilities that restrict hot work, hospitals, labs, food production, don’t need to schedule around a permit window. Crews can press connections during normal working hours instead of after-hours fire-watch shifts. Facility managers overseeing multiple buildings often standardize on MegaPress for exactly this reason: fewer scheduled shutdowns means fewer tenant notices and less coordination overhead across a portfolio.
