In industries where systems operate under extreme pressure, the reliability of every connection becomes critical. Components used in ultra high pressure systems must withstand intense forces without leaking or failing. This is where cone and threaded connections come into play. Known for their durability and precision sealing capability, these connections are widely considered one of the most dependable solutions for metal-to-metal sealing in high-pressure applications.
From high pressure tubing systems to waterjet cutting equipment, cone and threaded technology ensures a strong, leak-free connection even under pressures reaching 100,000 PSI.
What Are Cone and Threaded Connections?
Cone and threaded connections are specialized high-pressure fittings designed to create a secure metal-to-metal seal between tubing and connection components. Instead of relying on soft seals or gaskets, this technology uses precision-machined metal surfaces that fit together tightly.
The system works by combining two important elements:
A coned tubing end that creates the sealing surface
A threaded collar and gland that holds the connection tightly in place
When tightened, the coned surface presses firmly into the fitting seat, creating a powerful metal-to-metal sealing connection that can withstand extreme pressure.
This design makes cone and thread fittings ideal for demanding industrial environments where reliability and safety are essential.
Why Metal-to-Metal Sealing Is Stronger
Traditional sealing systems often rely on rubber or polymer seals that can degrade over time. In contrast, metal-to-metal sealing technology offers superior strength and durability.
Key advantages include:
Higher pressure tolerance for ultra high pressure systems
Improved resistance to temperature changes
Longer service life compared to soft-seal connections
Reduced risk of leakage in extreme environments
Because the sealing surface is made entirely of metal, cone and threaded high pressure fittings maintain their integrity even in applications where pressure cycles occur frequently.
This is especially important in industries using high pressure hydraulic systems or waterjet cutting machines.
Applications of Cone and Threaded Connections
Due to their strength and reliability, cone and threaded fittings are used across multiple high-pressure industries.
Common applications include:
Ultra high pressure waterjet systems
High pressure tubing installations
Hydraulic testing equipment
Oil and gas high pressure pipelines
Industrial pressure testing systems
In these applications, even a minor leak can lead to safety hazards or equipment damage. That's why engineers prefer cone and thread high pressure connections for systems operating at extremely high pressure levels.
Compatibility with High Pressure Components
One of the biggest advantages of cone and threaded connections is their compatibility with other ultra high pressure components. These connections integrate seamlessly with:
Ultra high pressure tubing

High pressure adapters
High pressure fittings
When properly installed, these components work together to create a complete high pressure fluid system capable of handling pressures up to 100K PSI or more.
The precision design ensures that each connection maintains a secure seal even under vibration, pressure spikes, or repeated use.
Benefits of Using Cone and Threaded Technology
There are several reasons why engineers and industrial operators prefer cone and threaded metal-to-metal sealing systems.
Major benefits include:
Exceptional strength for ultra high pressure applications
Reliable sealing without additional gaskets
High durability in harsh environments
Reduced maintenance and downtime
Superior performance in 100K PSI systems
Because of these advantages, cone and threaded fittings for high pressure tubing have become a standard solution in industries that demand maximum reliability.
