Coliter®’s compression rings (GJ3020) are precision-engineered brass ferrules designed to create secure, leak-free seals in compression-type plumbing fittings for copper and plastic tubing. Made from high-quality lead-free brass, these rings work with standard compression nuts to provide reliable radial compression against the pipe surface—ensuring long-term sealing performance under PN16 (1.6 MPa) pressure and temperatures up to 120°C. Ideal for residential water supply lines, radiator connections, and HVAC installations where soldering is impractical. Compatible with ISO-compliant compression systems and backed by strict quality control for consistent performance in potable water applications.
