Nibco PC-585-70-66-NS-2 Press Ball Valve 2 in 316SS

Product Description

The NIBCO PC-585-70-66-NS-2 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 form a permanent, watertight seal without flame, solder, or flux. A press-fit tool compresses the fitting onto the tube in seconds, making connections faster and safer than traditional soldered joints. When properly crimped, a unique N witness mark becomes visible, confirming a complete and secure connection. This valve is suited for licensed plumbers and pipefitters working on commercial and residential piping installations where quick, reliable shutoff is required.

The PC-585-70-66-NS-2 is intended for use in press-fit piping systems where 316 stainless steel construction is specified for corrosion resistance or system compatibility. At 2 inches, it fits larger-diameter lines common in commercial plumbing, hydronic heating, and industrial fluid control applications. It is part of the NIBCO Press System, which includes a full range of copper fittings, bronze valves, pressing tools, jaws, and chains, allowing contractors to work within a single, coordinated system.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with press-fit systems and the applicable IPC or local plumbing code requirements. Shut off and depressurize the line completely before servicing or installing this valve. Use only a compatible press-fit tool with the correct jaw size for a 2-inch connection to ensure proper crimp depth and O-ring engagement. Verify the N witness mark is visible on all connections before restoring system pressure.
