60-1257 Fireye UNION

Overview

The Fireye 60-1257 is a specialized 1/2 inch NPT sealing union with a quartz window, specifically engineered for industrial burner management and flame safeguard systems. It serves as a critical pressure-tight barrier between a flame scanner and the burner sight pipe, protecting sensitive electronics from positive furnace pressure and combustion byproducts while allowing for an unobstructed view of the flame.

Features

• High-purity quartz window ensures maximum ultraviolet (UV) light transmission for accurate flame sensing.
• Pressure-tight seal capable of withstanding positive furnace pressures up to 100 PSI.
• Durable industrial construction prevents leaks and protects scanner components from harsh combustion gases.
• Standardized 1/2 inch NPT threaded connection for secure and straightforward installation on rigidly fixed sight pipes.
• Supports safe ignition sequencing and continuous combustion monitoring.

Applications

The 60-1257 is primarily designed for use with Fireye UV1A flame scanners, though it is also compatible with UV2, 45UV3, UV8A, and UV90 series detectors requiring a 1/2 inch NPT connection. It is extensively used in industrial and commercial combustion environments, including boilers and process control systems, where monitoring flame stability under high-pressure conditions is essential for operational safety.
