Thermocouple Compression Fittings - NPT Thread

Thermocouple Compression Fittings with NPT threads provide a reliable, adjustable mounting solution for thermocouple probes in industrial temperature measurement applications. Designed for durability, precision, and ease of installation, these fittings ensure secure probe positioning while maintaining a tight, leak-resistant seal.

Manufactured from high-quality 316 stainless steel and engineered with precision-machined components, these compression fittings are ideal for use in high-temperature, high-pressure, and corrosive environments where accuracy and reliability are essential.

Designed for Secure Thermocouple Installation

Proper mounting is critical for achieving accurate and repeatable temperature measurements. These NPT thread compression fittings are designed to securely hold thermocouple probes in place while allowing for precise adjustment of insertion depth.

This ensures:

• Consistent probe positioning within the process

• Stable temperature readings over time

• Reduced risk of probe movement or vibration

• Reliable long-term performance

The adjustable design allows users to fine-tune sensor placement during installation, helping optimize measurement accuracy for specific applications.

Standard NPT Thread for Easy Integration

These compression fittings are available with industry-standard NPT male threads, making them easy to install in a wide range of systems.

Available thread sizes include:

• 1/8" NPT male

• 1/4" NPT male

• ½” NPT male

NPT threading provides a tapered seal that helps prevent leaks when properly installed, making these fittings suitable for use in pressurized systems and process environments.

Their compatibility with standard threaded ports allows for quick integration into:

• Pipes and tubing

• Process vessels and tanks

• Equipment housings

• Industrial systems and instrumentation setups

Adjustable Compression Design

The compression fitting design allows thermocouple probes to be inserted and secured at the desired depth, providing flexibility for different measurement requirements.

Key benefits include:

• Adjustable immersion depth for optimized readings

• Secure clamping to prevent probe movement

• Easy repositioning without removing the fitting

• Simplified installation and maintenance

This flexibility makes the fittings suitable for both permanent installations and applications where adjustments may be required over time.

Double Ferrule Design for Enhanced Sealing

These thermocouple compression fittings feature a double ferrule design for improved sealing and mechanical strength.

Advantages of double ferrules include:

• Stronger grip on the probe

• Enhanced leak resistance

• Improved performance under pressure and vibration

• Greater reliability in demanding environments

For smaller probe sizes, such as 1/16" (0.062") diameter thermocouples, a single ferrule design is used to ensure proper fit and performance.

Precision Machining for Reliable Performance

Each compression fitting is manufactured with precision machining processes to ensure consistent quality and performance.

Key manufacturing features include:

• Threads cut on CNC turning centers for accuracy and consistency

• Bore-through design for unobstructed probe insertion

• Bores drilled and reamed for smooth internal surfaces and precise dimensions

• Burnished ferrule seats to ensure proper seating and sealing

These precision manufacturing techniques help ensure that each fitting provides a secure, reliable connection while maintaining optimal probe alignment.

316 Stainless Steel Construction

These compression fittings are constructed from 316 stainless steel, offering excellent resistance to corrosion and harsh process conditions.

Benefits of 316 stainless steel include:

• High resistance to corrosion and oxidation

• Compatibility with a wide range of chemicals and fluids

• Strength and durability in high-temperature environments

• Long service life in industrial applications

This makes the fittings suitable for use in industries such as oil and gas, chemical processing, food and beverage, and power generation.

Supports Accurate Temperature Measurement

A properly mounted thermocouple probe is essential for obtaining accurate temperature readings. These compression fittings help maintain measurement integrity by:

• Holding the probe securely in position

• Preventing movement that could affect readings

• Ensuring consistent immersion depth

• Maintaining proper thermal contact with the process

By providing a stable and adjustable mounting solution, these fittings help ensure reliable and repeatable measurement results.
