72-20 Fireye UNION

Overview

The Fireye 72-20 is a 1-inch NPT galvanized, malleable cast iron union designed for use in industrial and commercial combustion systems. As a critical plumbing component in flame safeguard installations, it allows for the disconnection and reconnection of piping without requiring the rotation of the pipes themselves. This union is specifically engineered to provide a robust, leak-proof connection for sight tubes and other auxiliary piping associated with Fireye burner management systems.

Features

• Constructed from high-quality malleable cast iron for superior strength and durability in demanding environments.
• Hot-dipped galvanized finish provides excellent corrosion resistance against moisture and chemical exposure.
• Standard 1-inch NPT threaded ends ensure compatibility with industrial piping and Fireye burner accessories.
• Ground joint design facilitates easy assembly and disassembly for maintenance or system reconfiguration.
• Heavy-duty build capable of withstanding the vibrations and thermal stresses typical of boiler room operations.

Applications

The Fireye 72-20 union is primarily used in the installation of flame safeguard controls and burner management systems. It is commonly employed to mount scanners or sight tubes to a burner’s sight pipe, allowing for easy removal of the detector for cleaning or inspection. It is also suitable for general industrial plumbing where a reliable, corrosion-resistant union is required for gas or light oil fuel lines in commercial heating and process burner applications.
