Product Details

Description

This 1-1/4" x 1-1/4" x 3/4" black malleable iron tee is a high-durability reducing fitting designed for reliable plumbing and gas line applications. Primarily used to branch a smaller 3/4" line from a main 1-1/4" run, this tee is essential for connecting various household and commercial appliances to gas or liquid supply systems. Its heavy-duty malleable iron construction provides excellent tensile strength, while the precision-machined NPT threads ensure a secure, leak-resistant connection. Ideal for HVAC technicians and DIY homeowners alike, this fitting is a staple for installing or repairing supply lines for high-output appliances like furnaces, boilers, and large water heaters. The black finish is specifically suited for low-pressure gas, oil, and air applications, offering a professional-grade solution for appliance infrastructure.
