Top 5 Benefits of Medium-Pressure Fittings for Critical Industrial Applications

Medium-pressure fittings are essential components in fluid and gas systems across a range of industries, offering reliable, leak-tight connections for applications operating at pressures up to 20,000 psig (1378 bar). Designed for performance and durability, these fittings are critical in environments where secure, high-pressure connections are a must. 

What Medium-Pressure Fittings Matter
Medium-pressure fittings connect pipes, tubes, and hoses under moderate-to-high pressures while maintaining system integrity. Compared to traditional cone-and-thread fittings, which require precise preparation, specialized tools, and time-consuming alignment, Swagelok’s FK Series medium-pressure fittings install up to five times faster—minimizing installation, assembly, and maintenance time.

Why choose Swagelok's FK Series over cone and thread?

1. Faster,Easier Installation
   • Gaugeable, two-ferrule design simplifies installation and reduces the risk of error.
   • No specialized threading or coning required.
   
   
2. Reduced Leak Risk
   • Metal-to-metal seal that is less prone to vibration and thermal cycling.
   • Less prone to loosening compared to cone and thread.
   
   
3. Lower Maintenance
   • Reusable and easier to inspect.
   • Eliminates repeated re-torquing or re-threading.
   
   
4. Greater Safety
   • Minimizes installation errors and failure risk.
   • No lubricants or sealants required, avoiding contamination.
   
   
5. Cleaner System Integration
   • No thread sealants, ensuring compatibility with high-purity or sensitive systems.

Key Applications
Medium-pressure fittings support critical systems across industries:

• Oil & Gas – Hydraulic controls, wellhead panels, subsea equipment, chemical injection.
• Aerospace & Defense – Ground support, mobile military systems, aircraft fuel/hydraulic lines.
• Chemical & Petrochemical – Process instrumentation, high-pressure reactors, corrosive fluids.
• Power Generation – Turbine lubrication, steam/gas turbine instrumentation, nuclear monitoring.
• Research & Development – High-pressure testing, material evaluation, cryogenic systems.

The Bottom Line
Reliable, leak-free connections aren’t optional—they’re essential to system performance, safety, and uptime. Swagelok’s FK Series medium-pressure fittings deliver speed, durability, and confidence where it matters most.
