RIDGID Rings for ProPress, C1 Kit (Model 28043)

Description RIDGID Rings for ProPress, C1 Kit (Model 28043) expand a Compact Series press tool to handle copper and stainless steel ProPress fittings in tight spaces. Some searches shorten this to RIDGID C1 jaws. The C1 swivel actuator rotates a full 360° and positions ±90° to the tube, so a technician can press a fitting in a spot a fixed jaw can’t reach. What the C1 Kit Includes Four ProPress rings, 1/2″, 3/4″, 1″, and 1-1/4″, cover the sizes most common on residential and light commercial copper runs. The kit also includes the C1 actuator itself and a carrying case built to keep all four rings organized and protected between jobs, so a technician isn’t digging through a toolbox to find the right size mid-job. Why the Swivel Actuator Matters A fixed jaw needs enough clearance to seat squarely on a fitting, which isn’t always available inside a wall cavity, behind a joist, or in a mechanical room packed with parallel runs. The C1 actuator swivels independently of the press tool body, so the operator can angle into the fitting without repositioning the whole tool. That matters most on retrofit and service work, where the pipe run was installed without a press tool in mind. On new construction, the same flexibility speeds up rough-in on runs with tight joist bays or crowded manifold walls, where a rigid jaw would require extra clearance cuts just to get square access. Compatible Press Tools The C1 Kit fits RIDGID Compact Series press tools: the RP100-B, RP200, and RP210. It’s built specifically for the compact tool line and isn’t interchangeable with RIDGID Standard Series jaws used on larger MegaPress steel pipe work, ProPress and MegaPress are different systems built for different pipe materials. Built From Precision-Machined Alloy Steel Each ring is machined from alloy steel for consistent, even compression around the fitting on every press. Even compression is what makes a ProPress joint code-compliant and leak-free without solder, flux, or an open flame, and it’s why RIDGID backs the C1 Kit with its Full Lifetime Warranty against defects in materials and workmanship. Inspecting Rings Before a Job A worn or damaged ring won’t deliver even compression, which risks a joint that looks pressed but isn’t fully sealed. Check each ring for visible wear, cracking, or deformation before a job, especially on rings that see daily use. Replacing a worn ring costs far less than a callback on a leaking joint after the wall is closed up. Where the C1 Kit Gets Used Residential plumbing retrofits, pressing copper lines in basements, crawl spaces, and behind finished walls without draining the system Commercial and institutional projects in occupied buildings, offices, schools, and healthcare facilities where a hot work permit would otherwise slow the job down Service calls in tight mechanical rooms where a standard jaw can’t get square access to the fitting New construction runs where flameless connections speed up rough-in without a fire watch Frequently Asked Questions Which tools are compatible with the RIDGID Rings for ProPress C1 Kit? RIDGID Compact Series press tools, including the RP100-B, RP200, and RP210. What’s included in the C1 Kit? Four ProPress rings, half inch, three-quarter inch, one inch, and one and a quarter inch, one C1 actuator, and a carrying case. Do the rings work with stainless steel fittings? Yes. The C1 Kit works with both copper and stainless steel fittings built for the ProPress system. Is this the same as RIDGID MegaPress? No. ProPress and MegaPress are separate systems. ProPress presses copper and stainless steel fittings, MegaPress presses carbon steel fittings, and the two use different jaws and rings. How do I know if a ring needs to be replaced? Check for visible wear, cracking, or deformation before each job. A worn ring can’t deliver even compression, which can leave a joint that looks pressed but isn’t fully sealed. Is the RIDGID C1 jaws the same as RIDGID Rings for ProPress? Yes. C1 jaws is a common shorthand for the C1 actuator and ring kit, both refer to Model 28043. ProPress connections should meet applicable plumbing code requirements, IAPMO maintains listings and standards relevant to press-fit systems.
