1/2 inch Cast Brass Tee Copper x Copper x Female

1/2 Inch Cast Brass Tee – Threaded Fitting for Pressure and Mechanical Piping Systems

The 1/2 inch cast brass tee is a three-way fitting used for branching pipe systems in potable water, HVAC, and mechanical piping installations. Manufactured from cast brass alloy, this tee features female NPT threads on all three ends, ensuring compatibility with threaded pipe and fittings in pressure-rated systems.

Material Composition and Performance Characteristics

This fitting is produced using lead-free cast brass, typically conforming to ANSI/NSF 61 and NSF 372 standards for potable water applications. Brass provides a balance of tensile strength, thermal conductivity, and corrosion resistance, making it suitable for long-term use in a range of fluid handling systems. Key technical attributes include:

• ✅ Machined NPT Threads – Female National Pipe Tapered (NPT) threads ensure a secure seal with compatible threaded pipe.
• ✅ Pressure-Rated Design – Suitable for cold and hot water distribution lines under standard residential and commercial pressure conditions.
• ✅ Lead-Free Compliance – Certified for use in potable water systems; meets Safe Drinking Water Act requirements.
• ✅ Corrosion Resistance – Brass resists dezincification and common plumbing system corrosion, especially in fluctuating temperature environments.
• ✅ High Thermal Stability – Operates effectively in high-temperature domestic water and heating systems.

Installation Guidance

This tee installs into piping systems using standard pipe wrenches and approved thread sealing methods such as PTFE tape or non-hardening pipe joint compound. Avoid overtightening to protect the integrity of the threads and ensure correct alignment with other system components. Ensure thread engagement depth follows ASME B1.20.1 standards.

Product Specifications

Material and Industry Note

Brass is widely accepted for use in plumbing and mechanical codes due to its long service life, machinability, and resistance to corrosion and thermal expansion. Its use is supported by IPC and UPC code tables for threaded fittings in potable and hydronic systems.

Manufacturing and Inspection Standards

Each fitting is manufactured to comply with applicable ASTM and ASME dimensional standards and undergoes pressure and dimensional testing prior to distribution. Batch traceability and certification are typically available upon request for code-driven projects or regulated facilities.
