Brasscraft Bc-63-6-8wx Cd Compression Adapter Fitting

Product Description

The BRASSCRAFT bc-63-6-8wx cd is a compression adapter fitting designed to connect tubing of two different sizes in plumbing supply line applications. It transitions a 1/2 inch compression inlet to a 3/8 inch compression outlet, allowing a licensed plumber or skilled tradesperson to join dissimilar supply lines without soldering or additional fittings. This type of adapter is a standard component in residential and light commercial plumbing rough-in and finish work, particularly when connecting fixture supply lines to shutoff valves or branch supply tubing.

This compression adapter is used where a 1/2 inch supply line must be reduced or transitioned to a 3/8 inch compression connection. Common applications include under-sink installations for faucets, toilets, and similar fixtures where existing rough-in pipe size differs from the fixture supply connection size. It is well suited for residential plumbing service calls, new construction finish plumbing, and retrofit work on existing supply lines.

Key Features

• 1/2 inch compression inlet to 3/8 inch compression outlet configuration
• No-solder compression connection on both ends for tool-accessible installation
• Suitable for residential and light commercial supply line applications
• Manufactured by BRASSCRAFT, a recognized plumbing fittings brand

Compatibility

Designed as an OEM-style compression adapter for residential plumbing supply line installations where a 1/2 inch to 3/8 inch size transition is required.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and relieve line pressure before beginning any fitting work. Hand-tighten the compression nuts first, then snug with a wrench — do not overtighten, as over-compression can crack ferrules or distort tubing. Inspect for leaks after restoring water pressure.
