Instrumentation Fittings

Instrumentation Fittings for Precision Industrial Connections

Instrumentation fittings are essential components in process and control systems where accurate, leak-free connections are critical. Commonly used in oil and gas facilities, chemical processing, power generation and manufacturing plants, these fittings connect tubing and piping systems that transmit pressure, gas or fluid signals. Their design supports high-pressure service and helps maintain system integrity in demanding industrial environments.

Construction and Performance

Instrumentation fittings are typically made from stainless steel or other corrosion-resistant materials to maintain strength and performance under high temperature and pressure conditions. They are engineered to deliver secure, vibration-resistant connections, making them suitable for both dynamic and static systems. Precision threading and uniform sealing surfaces allow these fittings to perform reliably in applications that demand exact control and measurement.

Common Types of Instrumentation Fittings

• Instrumentation Tube Fittings: Used to connect sections of tubing in measurement and control systems. Their compression-type design provides a tight, reliable seal without the need for welding.

• Instrumentation Pipe Fittings: Designed for use in pipe-based systems, providing connections between different pipe sizes or materials while maintaining pressure integrity.

• Instrumentation Connectors: Used to join various system components such as gauges, transmitters and valves, offering a stable connection for accurate signal transmission and control.

• Elbows, Tees and Adapters: Available in multiple sizes and configurations to support complex system layouts and routing requirements.

Industrial Applications

Instrumentation fittings are used in a wide range of industries including oil refineries, petrochemical plants, water treatment facilities and laboratory systems. Their ability to maintain leak-tight performance under varying pressure and temperature conditions makes them critical for process reliability and safety. In many setups, they work alongside Instrumentation Valves to provide a complete solution for flow control, monitoring and isolation.
