The MILWAUKEE 2-1/2" – 4” CTS-V Pivoting Press Ring Kit is designed for use with M18 FORCE LOGIC Press Tools on Viega ProPress, Apollo Press and other press fitting systems. The CTS-V Pivoting Press Ring Kit is a more efficient alternative to sweat and solder, enabling you to press connections on 2-1/2" – 4” copper and copper tube-sized (CTS) stainless steel pipe. Pivoting functionality delivers greater access in tight spaces when paired with the X5 Ring Jaw & M18 FORCE LOGIC Press Tools. Additionally, Milwaukee's press blocking system prevents improper ring and ring jaw mismatch providing peace of mind in quality connections. The 2-1/2" – 4” CTS-V Pivoting Press Ring Kit, combined with the ring jaw and in-line M18 FORCE LOGIC Press Tools, deliver unrivaled access in tight spaces and around installed pipes, providing you with controlled, flameless copper connections for unmatched productivity.
