Cambridge Brass Waterworks Products Copper Tube Size LF Brass Compression Curb Stop

Lead Free brass curb stops are installed on the property line of homes and small commercial properties. They provide an easily located buried on/off valve for the water utility operator to temporarily isolate a water service from the water distribution system in case of leaks or a delinquent water bill payment.

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 a curb stop with CB Compression ends is quick and easy. Copper tube or copper tube size HDPE is stabbed through the nut and gasket/friction ring assembly to the stab depth. The H nut is tightened, which compressed the EPDM 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 Ball Valve meet or exceed AWWA C800 and NSF 61 and 372 Standards.
