1-1/2 inch x 1-1/4 inch Black Iron 90 Degree Reducing Elbow Female x Female

1-1/2 inch x 1-1/4 inch Black Malleable Iron 90° Reducing Elbow – Threaded FPT x FPT

This 90° reducing elbow is manufactured from black malleable iron and is designed for use in threaded steel or iron piping systems. The fitting allows a change in direction while transitioning between 1-1/2 inch and 1-1/4 inch nominal pipe sizes. It is suitable for use in natural gas, LP gas, steam, air, and non-potable water systems.

Engineered to meet the requirements of ASME B16.3 and ASTM A197, the fitting features tapered female National Pipe Thread (NPT) ends to ensure a secure, pressure-rated seal. The black finish designates it for applications where galvanization is not required, such as indoor fuel gas and low-pressure heating systems.

Specifications

• Nominal Sizes: 1-1/2 inch x 1-1/4 inch
• Fitting Type: 90° Reducing Elbow
• Material: Malleable Iron (ASTM A197)
• Thread Standard: NPT – ANSI B1.20.1
• Pressure Class: Class 150 (per ASME B16.3)
• Finish: Black (non-galvanized)

Typical Applications

• • Fuel gas piping systems (natural gas, propane)
• • Low-pressure steam and hydronic heating circuits
• • Compressed air and vacuum lines
• • Industrial and commercial mechanical piping networks

Installation Notes

Thread sealant or PTFE tape should be applied to male threads prior to installation. Tighten fittings with standard pipe wrenches, avoiding over-torquing which can lead to thread deformation. Alignment and support of adjoining piping should follow applicable mechanical codes and manufacturer guidelines.

Material Performance

Malleable iron provides high tensile strength and thermal resistance, making it suitable for installations subject to thermal cycling and moderate mechanical stress. Black finish fittings are typically used indoors or in applications where exposure to moisture is controlled.
