The Mueller Streamline a07812nl is a no lead brass flush bushing designed for plumbing professionals who need a reliable, code-compliant transition fitting. This bushing connects a 1/2 inch FTG (male solder) end to a 1/8 inch female NPT threaded port. It is used in potable water systems, residential plumbing rough-in work, and light commercial applications where a compact, low-profile threaded reduction is required. The flush bushing design keeps the fitting close to the pipe or fitting body, saving space in tight installations and reducing the overall length of the connection assembly. This makes it a practical choice when working inside walls, equipment chases, or near fixture rough-in points where clearance is limited. The a07812nl is manufactured from C27451 alloy no lead brass, which meets federal and state no lead requirements for use in drinking water systems. Plumbers and pipefitters trust no lead brass fittings to stay compliant with NSF and Safe Drinking Water Act standards. The male solder end is sized for standard 1/2 inch copper tubing, making it compatible with Type K, L, and M copper pipe commonly found in residential and light commercial plumbing systems. The 1/8 inch FNPT (female national pipe thread) end accepts standard tapered pipe thread fittings, gauges, sensors, or plugs. This type of fitting is often used to tap into a copper line for a pressure gauge port, a drain valve, or a sensor connection. At just 0.03 pounds, the a07812nl is lightweight and easy to handle during installation. Mueller Streamline is a recognized name in the plumbing supply industry, known for producing consistent, high-quality brass fittings that meet trade standards.
The Mueller Streamline a07812nl flush bushing provides a compact, no lead brass solution for transitioning between a 1/2 inch solder fitting and a 1/8 inch female NPT connection in potable water and plumbing systems. Its low-profile design and code-compliant material make it a dependable choice for professional plumbers.
