Sioux Chief sc-685-c3 Straight Adapter 3/4 in Cpvc X Press-fit

Product Description

The SIOUX CHIEF sc-685-c3 is a straight adapter fitting designed to connect CPVC pipe to a press-fit copper end in a single inline transition. Manufactured domestically, this adapter measures 3-11/16 inches in length and is sized for 3/4 inch nominal pipe. It is part of the MetalHead line of transition fittings, which are built to provide a reliable mechanical connection between dissimilar pipe materials without soldering on the press-fit side. Plumbers and pipefitters install this fitting in both new construction and retrofit applications where CPVC supply lines meet copper distribution piping.

This adapter suits residential and light commercial plumbing systems where a direct in-line transition from CPVC to copper is required. Common install scenarios include domestic water supply rough-in, branch line connections, and repair work where existing copper press-fit infrastructure meets a CPVC run. The 3/4 inch nominal size covers the most frequently used residential supply line diameter.

Key Features

• Straight adapter configuration for direct in-line pipe transition
• CPVC socket inlet connects to standard 3/4 inch CPVC pipe
• Press-fit copper outlet eliminates the need for soldering on that end
• Domestic manufacture
• 3-11/16 inch overall length accommodates standard rough-in clearances

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 3/4 inch nominal CPVC-to-copper press-fit transitions in residential and light commercial plumbing systems.

Installation Notes

Installation is performed by licensed plumbers in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize the line before installation. Ensure CPVC pipe ends are cut square and deburred before seating into the CPVC socket, and verify the copper press-fit end is fully engaged before cycling pressure. Do not apply flame or heat to the CPVC side of this fitting.
