1" x 1" x 1/2" Black Malleable Iron Tee – For High-Integrity Branch Connections

The 1" x 1" x 1/2" black malleable iron tee is designed for threaded pipe systems requiring a dependable branch connection. Manufactured from ASTM A197 malleable iron and coated with a black oxide finish, this fitting provides durability and dimensional accuracy for gas, water, and air applications in both commercial and industrial settings.

Its configuration allows for two 1" mainline runs with a 1/2" outlet branch, supporting system extensions or pressure monitoring devices. The threads conform to ANSI B1.20.1 NPT standards, ensuring compatibility with standard schedule 40 steel piping.

Key Performance Characteristics

• ✅ Malleable Iron Construction Offers superior mechanical strength while maintaining formability for pressure-rated systems.
• ✅ Corrosion-Resistant Coating Black oxide finish enhances durability in environments where moisture or chemical exposure may occur.
• ✅ Threaded Female Ends NPT-compatible threads allow for consistent engagement and leak-resistant seals.
• ✅ Reduced Branch Size 1/2" side port provides compatibility for step-down connections and auxiliary system taps.

Specifications

• Material: Malleable Iron per ASTM A197
• Finish: Black (non-galvanized) oxide coating
• Size: 1" x 1" x 1/2"
• Thread Standard: NPT ANSI B1.20.1
• Pressure Rating: 150 psi max (per ANSI/ASME B16.3)
• Compliance: UL/FM approved for fire protection and potable water (if applicable with sealing compounds)

Installation Notes

For optimal performance, thread sealant or PTFE tape should be applied to all male-threaded pipe ends before mating with the fitting. Proper wrenching torque should be used to avoid over-tightening and potential thread distortion. Confirm alignment and support for all pipe sections before pressurizing the system.

Typical Applications

This reducing tee is widely utilized in hydronic heating loops, natural gas distribution lines, compressed air systems, and industrial process piping where branch connections require structural integrity and compact profiles. It supports both vertical and horizontal system configurations.

Did You Know?

Malleable iron fittings are annealed after casting to improve ductility, allowing them to absorb mechanical stress without cracking—unlike cast iron fittings that are more brittle under similar loads.

The 1" x 1" x 1/2" black malleable iron tee delivers the mechanical performance and dimensional precision demanded by professional contractors. Engineered to industry standards, it ensures lasting, leak-free installations in high-pressure threaded systems.
