Mueller Streamline a01572nl Tee Fitting C X C X Fpt 1 Inches X 1 Inches X 3/4 Inches Lead-free Cast Brass

Product Description

The Mueller Streamline a01572nl is a lead-free cast brass tee fitting designed for use in above-ground potable water supply and pressurized plumbing systems. This fitting features a C x C x FPT connection configuration, meaning it accepts two 1-inch copper pipes via cup solder joints on the run ends and connects to a 3/4-inch female pipe tapered thread (NPT) on the branch end. This combination makes it highly versatile for plumbers who need to branch off a main copper supply line and transition to a threaded connection in a single fitting. The tee is manufactured from a high-grade lead-free cast brass alloy, meeting the requirements for use in drinking water systems and complying with strict material safety standards. Mueller Streamline has been producing copper and brass solder-joint fittings for over 80 years, and this fitting reflects that long history of precision engineering and consistent quality. Plumbers, pipefitters, and mechanical contractors rely on Mueller Streamline fittings for their dimensional accuracy and reliable solder connections. The fitting weighs 0.42 pounds, making it easy to handle during installation in tight spaces such as wall cavities, under sinks, or in mechanical rooms. It conforms to multiple ASME standards including B16.15, B16.18, B16.22, B16.24, B16.50, and B1.20.1, ensuring it meets the dimensional and pressure-integrity requirements expected on professional plumbing jobs. Whether you are rough-in plumbing a new residential build, retrofitting a commercial water distribution system, or making a repair on an existing copper line, the a01572nl delivers the fit and finish that trade professionals depend on. This fitting is a go-to choice for any copper tee application requiring a threaded branch outlet.
