The NIBCO RG91100 is a push removal tool designed for disconnecting 1-inch push-to-connect fittings quickly and cleanly. Push-to-connect systems lock tubing in place with an internal collet and O-ring; this tool releases that collet without damaging the fitting body or the tubing. It is used during maintenance, repairs, or system modifications where push-fit connections need to be broken and potentially reused. Plumbers and HVAC technicians working with push-to-connect water supply or hydronic lines will find this tool fits the standard 1-inch connection size.
This tool is intended for use on 1-inch push-to-connect fittings commonly found in residential and light commercial plumbing, radiant heating systems, and water distribution lines. It is suited for any install scenario where push-fit fittings are used and a clean, non-destructive disconnect is required. The tool allows a technician to release the fitting collet evenly around the circumference, reducing the risk of tubing or fitting damage during removal.
Designed as an OEM-style removal tool for standard 1-inch push-to-connect fittings used in plumbing and hydronic applications.
Shut off the water supply and relieve system pressure before disconnecting any push-to-connect fitting. Insert the removal tool squarely around the tubing and press firmly against the fitting collar to release the collet before pulling the tubing free. This tool is typically used by licensed plumbers working under IPC or local plumbing code requirements. Do not force the tool at an angle, as uneven pressure may deform the collet or O-ring.
