3 inch x 2-1/2 inch Black Iron Bushing

3" x 2-1/2" Black Iron Bushing – Threaded Pipe Reducer for High-Strength Applications

This 3 inch x 2-1/2 inch black iron bushing is engineered for reducing pipe size within threaded systems. Commonly used in gas, steam, and low-pressure fluid systems, it provides a compact and secure method for transitioning between pipe diameters while maintaining system pressure integrity.

Contractor-Grade Construction and Design

Precision-machined to industry specifications, this bushing is suited for mechanical and plumbing systems that demand reliability under variable conditions. Key features include:

• ✅ NPT Threaded Ends Tapered threads provide secure engagement and seal compatibility for both male and female connections.
• ✅ Black Iron Material Cast from malleable iron and coated for corrosion resistance in dry or enclosed system environments.
• ✅ Pressure-Rated Design Capable of withstanding moderate internal pressures in structural and utility systems.
• ✅ Consistent Fitment Precision threading ensures uniform assembly in rigid pipe configurations.

Specifications

• Material: Black malleable iron
• Nominal Sizes: 3" male x 2-1/2" female NPT
• Connection Type: Threaded (MPT x FPT)
• Standard Compliance: Conforms to ASME B16.3 and B16.14 dimensional and material standards

Installation Guidelines

Apply an approved thread sealant or PTFE tape before engaging the fitting. Use standard pipe wrenches to achieve sufficient torque without over-tightening, which could lead to cracking or distortion. Proper installation practices are essential for maintaining thread integrity and preventing leaks under system pressure.

Application Overview

Typically installed in commercial and industrial systems where pipe size transitions are required, including mechanical rooms, compressed air lines, gas distribution systems, and utility infrastructure. The bushing’s compact profile is especially useful where space constraints limit the use of longer reducing fittings or unions.

Material Insight

Black iron fittings are preferred in gas and heating applications due to their tensile strength and resistance to thermal expansion. While not recommended for potable water, they are well-suited for venting, air, and fuel line applications under standard temperature and pressure ranges.

The 3" x 2-1/2" black iron threaded bushing offers a rugged, field-proven solution for contractors requiring reliable dimensional reduction within steel or iron piping systems. Designed to meet industry tolerances and installation expectations, it supports long-term performance in demanding applications.
