2 inch x 1 inch Galvanized Cast Iron Bushing

2 inch x 1 inch Galvanized Cast Iron Bushing – Threaded Reducer for Rigid Piping Systems

The 2 inch x 1 inch Galvanized Cast Iron Bushing is designed to reduce pipe size in threaded metallic piping systems. With both male and female NPT threads, this fitting allows a secure transition from a 2 inch FPT opening to a 1 inch MPT outlet, maintaining structural alignment and flow control. Constructed from malleable cast iron and coated with a hot-dip galvanized finish, the bushing is engineered for mechanical strength and corrosion resistance.

Suitable for non-potable water, compressed air, gas, and steam applications, this reducer bushing is used where size transitions are required in rigid piping runs while preserving system integrity under typical service conditions.

Product Features

• ✅ Malleable Iron Body – Manufactured to ASTM A197 standards for strength and dimensional stability under mechanical loads.
• ✅ Hot-Dip Galvanized Coating – Provides resistance to corrosion in wet or humid environments, extending system service life.
• ✅ Threaded NPT Connections – Compliant with ASME B1.20.1 specifications for compatibility with steel and iron threaded pipe systems.
• ✅ Compact Profile – Efficient for retrofits and space-constrained assemblies without adding significant bulk to pipe networks.
• ✅ Pressure Rating – Suitable for low- to medium-pressure applications per ASME B16.3 guidelines when installed correctly.

Installation Guidelines

Apply thread sealant or PTFE tape to the male threads before installation. Use a pipe wrench on the flats of the bushing, not the outer rim, to prevent deformation. Do not overtighten to avoid thread galling or cracking. Ensure proper alignment with mating fittings to maintain system pressure integrity and code compliance.

Technical Specifications

• Material: Galvanized cast malleable iron
• Connection Type: NPT Female (2 inch) x NPT Male (1 inch)
• Size: 2 inch x 1 inch nominal
• Standards: ASME B16.3, ASTM A197, ANSI/ASME B1.20.1

Typical Applications

Used in mechanical rooms, industrial piping layouts, and utility systems where reducing connections are required. Common in gas distribution piping, fire sprinkler risers, hydronic heating lines, and non-potable water supply branches. Not intended for potable water systems unless fittings meet NSF certification requirements.

Material Overview

Galvanized cast iron combines strength with corrosion resistance, making it appropriate for applications where fittings are exposed to condensation, atmospheric moisture, or mild chemical environments. The malleable structure absorbs vibration and accommodates thermal expansion without loss of thread integrity.

The 2 inch x 1 inch Galvanized Cast Iron Bushing is a code-compliant, industry-standard fitting designed for permanent transitions between pipe sizes in rigid metal piping networks. Its rugged construction and dimensional accuracy support performance across a wide range of commercial and industrial systems.
