Sioux Chief sc-685-c4 1 Inch Cpvc X Press-fit Adapter

Product Description

The SIOUX CHIEF sc-685-c4 is a straight adapter fitting designed to transition between CPVC pipe and a copper CTS press-fit connection. Built as a lead-free (LF) fitting, it meets potable water safety requirements for residential and commercial plumbing installations. The adapter features a CPVC socket end on one side and a male CTS MetalHead press-fit end on the other, allowing a tool-based press connection to copper tubing without soldering. Licensed plumbers install this type of fitting when connecting CPVC supply lines to copper press-fit systems during new construction or retrofit work.

This adapter is suited for potable water supply systems where CPVC pipe meets a copper press-fit distribution network. It is commonly used in residential and light commercial plumbing where code requires lead-free materials in water supply lines. The 1-inch nominal size covers a standard pipe size found in main supply branches and larger distribution runs. Its MetalHead press-fit end is designed to accept standard CTS press tooling used by plumbing professionals.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully depressurize and drain the line before installing this fitting. The CPVC socket end requires approved CPVC solvent cement applied per the cement manufacturer's instructions, and the press-fit end requires a compatible CTS press tool with the correct jaw size. Do not use open flame or heat near CPVC pipe during or after installation of the press-fit end.
