1-1/2 inch x 1/2 inch x 1-1/4 inch Black Malleable Iron Reducing Tee – Threaded Fitting for Multi-Size Pipe Connections

The 1-1/2 inch x 1/2 inch x 1-1/4 inch Black Malleable Iron Reducing Tee is engineered for use in threaded piping systems where multiple pipe diameters converge. This tee fitting provides a reliable method to branch a smaller line from larger pipelines while maintaining system integrity. Built from high-strength malleable iron and treated with a black oxide coating, it is designed to withstand the demands of low- to medium-pressure steam, air, gas, or liquid distribution systems.

Technical Features

• Material: Black malleable iron conforming to ASTM A197
• Finish: Black oxide for added corrosion resistance in non-potable applications
• Connection Type: Female NPT (National Pipe Thread) x Female NPT x Female NPT
• Sizes: 1-1/2 inch x 1/2 inch x 1-1/4 inch
• Standards: ASME B16.3 and UL/FM compliance for applicable systems

Performance and Application Advantages

• Pressure Rated: Suitable for use in systems operating up to 150 psi for steam and 300 psi for water, oil, and gas (WOG).
• High Dimensional Accuracy: Machined to precise tolerances for consistent thread engagement and tight seals.
• Reduced Installation Time: Threaded design allows for fast, secure connections without welding or flanging.
• Versatile Configuration: Designed to adapt varying pipe diameters for branch lines without using multiple reducers or adapters.
• Corrosion Resistant Coating: The black finish provides moderate protection in indoor and dry environments.

Use Cases

This reducing tee is commonly used in industrial, mechanical, and residential settings for distributing gas, air, oil, or non-potable water. Ideal for retrofits, boiler room layouts, air compressor lines, and low-pressure process piping, it enables compact layouts and efficient directional transitions.

Installation Guidelines

Installation should follow standard NPT thread practices. Use thread sealant or PTFE tape to ensure leak-free operation. For best results in pressure-rated applications, hand-tighten followed by appropriate wrench torque. Always pressure-test after installation to confirm system integrity.

Did You Know?

Malleable iron offers high tensile strength and impact resistance, making it a superior choice for threaded fittings compared to cast iron in dynamic or vibration-prone systems.

Choose the 1-1/2 inch x 1/2 inch x 1-1/4 inch Black Malleable Reducing Tee when your job demands multi-size integration with proven strength and dependability. This fitting is built for demanding environments where dimensional compatibility, performance, and code compliance matter.
