Swagelok® Medium-Pressure Tube Fittings (FK Series)
Swagelok FK series medium-pressure fittings have improved fluid connections in tough applications like oil and gas exploration, R&D systems, and the hydrogen market. They offer reliable, leak-tight connections for advanced systems in fluid handling and gas sealing applications.
View All Medium Pressure Tube FittingsSwagelok® FK series medium-pressure fittings install up to five times faster than cone and thread fittings, reducing installation time, assembly, and maintenance costs. The fittings are vibration-resistant and offer a leak-tight gas seal for applications up to 20 000 psig (1378 bar). Ideal for use in challenging environments where secure, high-pressure connections are critical.
These medium pressure fittings are reliable and efficient, offering robust performance in severe applications while protecting workers and the environment. They meet EC-79 standards for hydrogen applications up to 700 bar (10 150 psig) and feature a preassembled cartridge for easy, accurate installation. The simple two-piece design, with color-coded ferrules, ensures proper orientation and installation using standard tools. The strain-hardened 316 stainless steel body provides a lightweight, space-saving solution. FK series fittings are also available in NACE MR0175/ISO 15156 compliant versions.

Empa and Swagelok’s Collaborative Research Fuels Development of Hydrogen Transportation Innovations
The Swiss Federal Laboratories for Materials Science and Technology (Empa) and Swagelok are exploring the viability of hydrogen-based transportation solutions. One recent research breakthrough stemming from our collaboration incorporated Swagelok’s FK series fittings within the Empa hydrogen solution. Using FK series fittings instead of traditional Swagelok tube fittings significantly eased installation, while improving leak-tightness, reliability, and safety.
FK Series Medium-Pressure Tube Fittings
From initial construction and commissioning through daily operations and maintenance, there is a tremendous focus on reducing total lifecycle costs. FK series tube fittings can reduce maintenance costs and provide high reliability, reducing system downtime, when proper assembly processes are followed. These fittings can also help mitigate environmental impact via leak reduction as well as improve overall safety by protecting your system against corrosion.
