Brasscraft wc43-15 Flex Water Connector 3/4 in Swt X Fxm

Product Description

The BRASSCRAFT wc43-15 is a no-lead flexible water connector designed for potable water supply applications in residential and light commercial plumbing systems. Built with a sweat (SWT) inlet and a male flare (FXM) outlet, this connector provides a reliable, code-compliant transition between copper supply lines and fixtures or appliances. The no-lead construction meets federal and state regulations governing wetted components in drinking water systems. Licensed plumbers and pipefitters install this type of connector during fixture rough-in and final trim work where a flexible connection is needed to absorb minor misalignment or vibration between rigid supply lines and fixed equipment.

This connector is suited for potable water supply lines serving faucets, toilets, water heaters, and similar fixtures in residential and light commercial installations. The 3/4-inch SWT end sweats directly onto copper tubing, while the FXM end threads onto standard male flare fittings. The flexible construction allows for small positional adjustments during final connection without stressing rigid piping.

Key Features

• No-lead construction meets federal Safe Drinking Water Act requirements for wetted components
• 3/4-inch sweat (SWT) inlet for direct solder connection to copper supply tubing
• FXM (male flare) outlet for standard flare fitting connections
• Flexible body accommodates minor misalignment and reduces vibration transmission
• Suitable for potable water supply service in residential and light commercial systems

Compatibility

Designed as an OEM-style replacement flexible water connector for residential and light commercial plumbing systems requiring a 3/4-inch sweat to male flare (FXM) transition on potable water supply lines.

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 beginning work. The SWT end requires standard copper soldering practices — use lead-free solder and flux rated for potable water service. Do not overtighten the FXM threaded connection; use only hand-tight plus the appropriate turns as specified by the fitting manufacturer to avoid deforming the flare seat.
