Introduction to Instrument Fittings and Applications

We specialize in manufacturing Instrument Fittings and Stainless Steel Tube and Pipe Fittings for a variety of Instrumentation Applications. These fittings play a vital role in transmission, measurement, and control systems, specifically for flow, pressure, and temperature regulation. By offering a standardized approach, our fittings ensure reliable performance across different systems.

Main Elements of an Instrumentation System

An instrumentation system is composed of three key elements: fittings, valves, and tubing. These components are crucial for the proper functioning of systems in various industries. There are four primary types of high- to low-pressure tube fittings, distinguished by their end connections and applications:

Compression Fittings

Overview: Compression fittings are widely used for securing metal or hard plastic tubing. They rely on a ferrule design that compresses around the outer diameter (OD) of the tube to create a seal.
Components: These fittings consist of three parts—nut, body, and ferrule (either single or double).
Advantages: Well-suited for thinner walled tubing, compression fittings facilitate higher flow rates and are easier to bend and handle.

Cone and Thread Fittings

Overview: These fittings feature tube ends that are both coned and threaded. The threads help achieve a positive lock and seal between the tube end and the fitting body.
Applications: Frequently used in high-pressure systems, these fittings can handle pressures up to 15,000 PSI.

Butt Weld / Socket Weld Fittings

Overview: These fittings permanently join the tube ends by welding, ensuring a secure connection. This method is commonly used in high-pressure systems where a strong, permanent connection is required.

Instrumentation Fittings

Purpose: Instrumentation fittings are designed to connect straight sections of pipe or tubing, adapt to different sizes or shapes, and facilitate functions such as regulating or measuring fluid flow.
Applications: These fittings are essential in plumbing systems for controlling the flow of water, gas, or liquid waste in both domestic and commercial environments.

This is a comprehensive overview of various types of industrial fittings and their applications. Here's a brief breakdown of the mentioned categories:

Double Ferrule Compression Fittings: These fittings ensure a leak-proof connection by swaging the ferrules to the tube when tightened. Common configurations include male/female connectors, unions, elbows, tees, crosses, and bulkheads.
High Pressure Pipe Fittings: Designed for high-pressure applications (up to 10,000 psi), available in block and forged designs with tube and pipe connections.
Instrument Fittings – Pipe Fittings: Precision fittings for instrumentation, process, and fluid control systems. They come in various configurations and ensure leak-free performance.
Brass Compression Fittings: High-quality brass fittings ideal for instrument applications, available in heavy and light series, depending on the pressure requirements.
Weld Tube Fittings and Metal Gasket Face Seal Fittings: Leak-free metal-to-metal seal fittings, suitable for high-purity applications.
JIC Fittings: Comprising precision-machined components, including the body, sleeve, and nut, JIC fittings are commonly used in hydraulic and instrumentation systems.
Tube Inserts and Pipe Ferrule: Protect the tube ends in heat exchangers and other systems requiring tube mouth protection.
PTFE Compression Fittings and Valves: Fittings and valves made of PTFE, known for their durability and chemical resistance.
LP, MP, HP, and TYPE M Fittings: High-pressure fittings available in various configurations, suitable for low, medium, and high-pressure applications.
Flange to Compression Tube Adaptors: Directly connect flange pipes to tubes, available in various materials.
Tube Clamps: Available in standard, heavy, and twin series, these clamps are designed for securing tubes as per DIN 3015 standards.
Flareless Bite Type Fittings: These fittings “bite” into the tube to create a seal, available in carbon steel, brass, and stainless steel.
ORFS Fittings (O-Ring Face Seal Tube Fittings): Designed for sealing liquids and gases, these fittings work with both tubing and pipes, ensuring versatility.
Titanium Fittings & Valves: Used in high-performance applications, titanium fittings are lightweight, durable, and resistant to corrosion.
Duplex 2205 & Super Duplex 32750 Valves & Fittings: These fittings provide excellent corrosion resistance and strength, suitable for demanding environments.
