1 Inch Cast Brass Reducing Tee – Lead-Free, Pressure-Rated Fitting

The 1 inch x 3/4 inch cast brass reducing tee is a forged and machined plumbing fitting used for branching pipe systems of varying diameters. Constructed from lead-free brass alloy, this tee provides a durable and corrosion-resistant solution for potable water, mechanical piping, and hydronic heating systems. It includes two 1 inch inlets and a 3/4 inch reduced outlet (or vice versa depending on orientation), making it suitable for both new installations and system retrofits requiring size transitions.

Material Characteristics and Compliance

Manufactured from lead-free brass in compliance with the Safe Drinking Water Act (SDWA), this fitting meets NSF/ANSI 61 and NSF 372 requirements for use in potable water applications. Brass provides high resistance to dezincification, thermal stress, and chemical corrosion, especially in chlorinated or high-temperature systems.

• ✅ Lead-Free Certification – Conforms to federal and state plumbing code requirements for drinking water systems.
• ✅ Corrosion Resistant – Suitable for use in environments with variable pH, temperature, and pressure conditions.
• ✅ Pressure Rated – Compatible with standard pressure classifications; verify rating per application type.

Fabrication Standards and Connection Design

This tee is manufactured using precision casting and CNC-machining processes to ensure tight thread tolerances and consistent dimensional conformity. Threads meet ASME B1.20.1 standards, facilitating proper sealing with pipe dope or PTFE tape during assembly.

• ✅ Connection Type: Threaded or sweat connections depending on configuration (e.g., FIP x FIP x FIP or C x C x C)
• ✅ Nominal Size: 1 inch x 3/4 inch
• ✅ Wall Construction: Schedule-dependent brass wall thickness for mechanical durability
• ✅ Finish: Uncoated brass; suitable for concealed or exposed installations

Installation Practices

Use approved sealant (thread compound or PTFE tape) on male threads to prevent leakage. Tighten using a wrench on the fitting body only—avoid over-torqueing to preserve thread integrity. For sweat configurations, clean and flux mating surfaces prior to soldering with lead-free solder. Allow proper cooling before pressurizing the system.

Intended Use and Applications

Commonly installed in copper or brass piping systems for domestic water distribution, manifold setups, and branch takeoffs in commercial and residential plumbing layouts. Suitable for both vertical and horizontal pipe runs. The reducing configuration simplifies transitions between mainlines and branch pipes of differing diameters.

Industry Note

Lead-free brass fittings have been mandated for potable water systems under federal law since January 2014. These fittings are now standard in all compliant systems and are essential for inspection and occupancy approvals in regulated jurisdictions.
