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.
