Nibco PC-585-70-66-NS-34 Press Ball Valve 3/4 in 316SS

Product Description

The NIBCO PC-585-70-66-NS-34 is a 316 stainless steel ball valve designed for press-to-connect (PxP) piping systems. It uses an inboard bead and EPDM O-rings to create a permanent, watertight seal without flame, solder, or flux. A licensed plumber or mechanical contractor installs it using a compatible press-fit tool: applying tool pressure compresses the O-ring onto the tube and completes the joint in seconds. A unique witness mark becomes visible on the fitting once the crimp is properly made, confirming a correct installation. This valve is suited for residential and commercial plumbing applications where fast, reliable shut-off and flow control are required.

The PC-585-70-66-NS-34 is intended for use in press-fit copper tube systems at 3/4 inch connection size. Its 316 stainless steel body makes it appropriate for applications where corrosion resistance is a priority, such as domestic water distribution, hydronic heating, and light commercial plumbing. The press end connection style is compatible with standard NIBCO Press System tooling, jaws, and chains. It is part of a full system that includes copper fittings, bronze valves, and accessories designed to work together.
