High-Pressure Cone & Thread Fittings – Precision Sealing Solutions

Swagelok High-Pressure Cone & Thread Fittings are engineered for critical fluid systems that demand leak-tight, rugged connections at extreme pressures. These cone-and-thread fittings are designed to support service up to 60,000 psig (4134 bar) and are ideal for high-pressure instrumentation circuits, hydraulic systems, test stands, and specialty gas applications where traditional fittings cannot reliably perform.

The cone-and-thread design features precision-machined 316 stainless steel construction and a robust sealing geometry that creates a metal-to-metal seal capable of handling shock, vibration and repeated pressure cycling without compromising performance.

These fittings require skilled installation — the tube end must be properly threaded before assembly — to achieve optimal sealing and avoid leaks in high-pressure service.

Key Characteristics

• Extreme pressure ratings: Up to 60,000 psig (4134 bar) for demanding high-pressure systems.
• Durable 316 stainless steel materials for corrosion resistance and long service life.
• Precision cone-thread sealing delivers reliable leak control in critical applications.
• Application flexibility in oil & gas testing, high-pressure hydraulics, specialty gas dispersion, and engineering test rigs.

Typical Applications

These fittings are used where system integrity at high pressure is essential—such as:
✔ High-pressure instrumentation lines
✔ Hydraulic power units and test benches
✔ High-pressure gas distribution
✔ Research and development test loops

Design Features for Reliable Performance

A high-performance cone and thread fitting is engineered with several critical components to ensure safe and leak-tight operation:

These features work together to create a robust metal-to-metal seal suitable for high-pressure service.

Tubing Requirements

When using cone and thread fittings, cone- and thread-specific tubing is required. This tubing typically features:

Proper tubing selection is critical to achieving optimal performance and maintaining system safety.
