Instrumentation Tube Fittings

An Instrumentation Tube Union is a straight tube-to-tube fitting designed to connect two lengths of tubing in a secure, leak-tight, and high-integrity manner. Commonly used in instrumentation and process control systems, this fitting enables precise and reliable fluid or gas connections without the need for welding or threading.

• Straight connection: Joins two tubes of the same size in a linear configuration.

• Double ferrule design: Ensures a strong, vibration-resistant seal that remains leak-tight under high pressure and temperature fluctuations.

• High-quality materials: Typically made from stainless steel (SS 316/316L), brass, or special alloys for excellent corrosion resistance and durability.

• Easy installation: Reusable and requires only basic tools for assembly, saving time and effort during maintenance.

• Precision-machined: Guarantees consistent tube alignment and system integrity in demanding applications.

• Oil & gas instrumentation lines

• Chemical and petrochemical plants

• Power generation systems

• Laboratory and analytical equipment

• High-purity fluid systems

• Hydraulic and pneumatic controls

• Available tube sizes: From 1/8" to 1" or 6 mm to 25 mm

• Pressure rating: Suitable for medium to high-pressure applications (varies by size and material)

• Standards: Typically conforms to ASTM, ASME, ISO, or equivalent industrial standards

An Instrumentation Tube Union Cross is a four-way precision tube fitting designed to connect four sections of tubing in a cross (X-shaped) configuration. It allows for fluid or gas distribution in multiple directions within instrumentation and process control systems, maintaining a high-integrity, leak-proof connection.

• Four-port connection: Joins tubing in two perpendicular directions, enabling complex flow distribution in compact layouts.

• Double ferrule compression fitting: Ensures leak-tight performance under high pressure and vibration conditions.

• High-grade materials: Commonly manufactured from stainless steel (SS 316/316L) or other corrosion-resistant alloys to withstand harsh environments.

• Precision engineering: Provides accurate tube alignment and secure sealing for critical applications.

• Reusable and easy to assemble: No welding or threading required; allows quick installation and maintenance.

• Instrumentation panels and manifolds

• Chemical and petrochemical process lines

• Oil & gas instrumentation systems

• Laboratory and analytical setups

• Pneumatic and hydraulic control systems

• Tube sizes: Typically ranges from 1/8" to 1" (or 6 mm to 25 mm)

• Pressure rating: Designed for high-pressure applications, depending on size and material

• Standards compliance: Compatible with international standards like ASTM, ASME, ISO

An Instrumentation Tube Union Elbow is a precision-engineered pipe fitting used to connect two sections of tubing at a 90-degree angle in instrumentation and process control systems. Designed for high integrity and leak-proof performance, it allows smooth directional changes in tube runs without compromising pressure or flow characteristics.

• 90° elbow connection: Joins two tubes at a right angle for directional flow adjustment.

• Double ferrule design (commonly): Ensures a secure, leak-tight seal even under high pressure and vibration.

• Material options: Typically available in stainless steel (SS 316/316L), brass, or alloy variants for corrosion resistance.

• High precision machining: Ensures exact fit and reliable performance in critical applications.

• Ease of installation: Reusable and requires no special tools for assembly or disassembly.

• Oil & gas instrumentation lines

• Chemical and petrochemical plants

• Power generation and utilities

• Laboratory and analytical systems

• High-purity and hydraulic systems

• Tube sizes: Usually available from 1/8" to 1" or 6mm to 25mm

• Thread types (if applicable): NPT, BSP, or metric threads

• Compliance: Compatible with standards like ASTM, ASME, and DIN depending on manufacturer
