Sioux Chief 647-C2DW Cpvc Fip Winged Sillcock Adapter

Product Description

The SIOUX CHIEF 647-C2DW is a 1/2 inch CPVC to 1/2 inch female iron pipe (FIP) winged sillcock adapter used to connect CPVC supply lines to threaded sillcock valves in residential and light commercial plumbing systems. The integral mounting wings, also called ear wings, allow the fitting to be secured directly to a wall framing member or backing plate, providing stable support at the point of wall penetration. This adapter eliminates movement and stress on the CPVC line during hose bib use and winterization cycles. It is a standard fitting installed by licensed plumbers and plumbing contractors during new construction and remodel work.

This fitting is designed for use in residential potable water distribution systems where CPVC piping terminates at an exterior wall for a hose bib or sillcock connection. The winged design is particularly suited for new construction framing scenarios where the backing can be fastened before drywall installation. The 1/2 inch FIP outlet accepts standard threaded sillcock valves and hose bibs without additional adapters.

Key Features

• 1/2 inch CPVC inlet connects directly to CPVC supply pipe
• 1/2 inch FIP outlet accepts standard threaded sillcock and hose bib valves
• Integral mounting wings allow fastening to wall framing for rigid, movement-free installation
• Designed for potable water applications in residential and light commercial systems
• Compact form factor simplifies rough-in at exterior wall penetrations

Compatibility

Designed as an OEM-style replacement and new-installation fitting compatible with 1/2 inch CPVC piping systems terminating at a threaded sillcock or hose bib connection.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and depressurize the line before solvent-welding the CPVC socket connection. Use only CPVC-rated solvent cement and primer on the socket end, and allow full cure time before pressurizing the system. Secure the mounting wings to solid framing or blocking to prevent torque stress on the CPVC line when connecting or disconnecting the sillcock.
