Cambridge Brass Copper Tube Size LF Brass Compression X AWWA Main Stop Waterworks Products

Cambridge Brass Main Stops are available in 3/4″, 1″, 1-1/4″, 1-1/2″, and 2″ sizes with CB Compression Ends to fit copper pipe and CTS (copper tube size) high density polyethylene pipe.They can be installed in either a dry main or a main under pressure with a standard tapping machine or saddle. The large wrench flat assures ease of final adjustment in the main as well as ease in connecting the service line to the stop.

Copper tube size (CTS) pipe and fittings are often used with 3/4″ and 1″ service lines. Iron Pipe Size (IPS) pipes and fittings are more common for 1-1/4″, 1-1/2″ and 2″ service lines. Insert stiffeners are required for all connections using flexible plastic pipe.

Installing pipe into a  Cambridge Brass fitting with CB Compression ends is quick and easy. Copper tube or copper tube size HDPE (with insert) is stabbed through the nut and gasket/friction ring assembly to the stab depth. The H nut is tightened, which compressed the rubber gasket and stainless steel beveled gripper. This creates pull-out strength and a water tight seal. When used with copper tubing, the electrical conductor spring provides electrical contact between the pipe and the fitting. When used with HDPE the electrical conductor spring becomes purposeless.

These Cambridge Brass Corporation Stops are meet  or exceed AWWA C800 and  NSF 61 & 372 and are 300 PSI rated.
