3/8 inch x 1/4 inch Galvanized Cast Iron Bushing

3/8 inch x 1/4 inch Galvanized Cast Iron Bushing – Threaded Reducing Fitting for Durable Pipe Transitions

The 3/8 inch x 1/4 inch Galvanized Cast Iron Bushing is a reducing pipe fitting used to connect a larger female threaded opening to a smaller male pipe size. Engineered for strength and longevity, this bushing is commonly utilized in fluid and gas distribution systems where dimensional transitions are necessary without compromising system integrity.

Constructed from cast iron and hot-dip galvanized for enhanced corrosion resistance, this fitting meets the requirements of demanding environments such as mechanical rooms, industrial pipelines, and exposed service lines in utility applications. The precision-cut tapered NPT threads allow for consistent, tight-fitting seals across various system pressures.

Product Features

• Material: Galvanized cast iron per ASTM A-197/A-153 standards
• Connection: 3/8 inch Male NPT x 1/4 inch Female NPT
• Pressure Rating: Up to 300 PSI (dependent on system design and pipe schedule)
• Thread Standard: ANSI B1.20.1 NPT (National Pipe Thread – Tapered)
• Finish: Zinc-coated for improved corrosion resistance in wet or exposed locations

Application Use

This bushing is commonly used to reduce pipe size in plumbing, compressed air, oil distribution, and gas service systems. Its compact form factor allows for installation in confined spaces without compromising structural integrity. Suitable for use in conjunction with malleable iron fittings, steel piping, and other NPT-threaded components.

Installation Guidelines

Install using standard pipe wrench on the hex head only. Apply thread sealant or PTFE tape to male threads to ensure leak-free performance. Do not overtighten, as over-torquing may damage threads or lead to misalignment. Ensure fittings are aligned properly before pressure testing the system.

Field Note

Galvanized cast iron is favored for its strength and abrasion resistance, making it suitable for non-potable water, low-pressure steam, or air systems. Its use in outdoor and damp environments provides extended service life compared to uncoated iron fittings.

The 3/8 inch x 1/4 inch Galvanized Cast Iron Bushing offers a reliable transition between threaded pipe sizes while ensuring compliance with mechanical system specifications. Designed for use by professionals in construction, maintenance, and industrial piping networks.
