1" x 1/2" x 1/2" Black Malleable Iron Reducing Tee – Threaded Fitting for Gas and Mechanical Piping

The 1" x 1/2" x 1/2" Black Malleable Iron Reducing Tee is a three-way threaded fitting designed for applications requiring a change in direction while reducing the outlet size. Manufactured from ASTM A197 malleable iron and machined to ASME B16.3 standards, this tee provides a strong and leak-resistant connection for use in gas, steam, and low-pressure fluid systems.

It features a black iron finish suitable for use in above-ground systems not subject to corrosive or wet conditions. With female NPT threads on all three outlets (run and branch), this reducing tee allows easy integration with standard Schedule 40 or 80 steel pipe in both commercial and residential systems.

Contractor-Grade Features

• ✅ Cast Malleable Iron Body Delivers mechanical strength for high-temperature and moderate-pressure systems.
• ✅ Precision NPT Threads Engineered to ASME B1.20.1 for secure, pressure-tight seals when used with thread sealant.
• ✅ Reducing Configuration Accommodates transitions from a 1" main to two 1/2" branches for branch tie-ins and equipment feeds.

Installation Requirements

Ensure mating threads are clean and free of debris. Apply PTFE tape or pipe joint compound rated for iron fittings. Thread the tee into place by hand and complete tightening with a pipe wrench to the recommended torque. Avoid over-tightening to preserve thread integrity and maintain alignment.

Common Applications

Used in gas distribution, compressed air systems, and mechanical piping networks requiring compact branch connections. Frequently installed in boiler rooms, riser assemblies, and manifold layouts where size reductions and directional changes are required.

Material and Application Insight

Black malleable iron is ideal for non-corrosive applications where high strength and rigidity are required. It is not recommended for use with potable water or in corrosive or buried environments without additional protection.

The 1" x 1/2" x 1/2" Black Malleable Iron Tee offers dimensional accuracy, structural integrity, and compatibility with code-compliant piping systems. Designed for professionals, it ensures durable and reliable performance across a wide range of threaded pipe installations.
