The Tube Fittings Division (TFD) of Parker Hannifin Corporation, the global leader in motion and control technologies, will be introducing Seal-Lok™ Xtreme at the upcoming Power Gen International show, for power gen applications.

This O-ring face seal tube fitting is equipped with a patent-pending metal sealing ring that makes it ideal for applications where typical elastomeric sealing is not a possibility due to extreme temperature, including power generation application environments like combustion turbines.
Seal-Lok Xtreme has been extensively tested for thermal cycle and shock, and has performed well with helium mass spectrometer and gas pressure leak testing. This Parker innovation achieves superior tube and hose connections at working pressures of up to 5,850 psi with temperatures as low as -328°F (-200°C) and as high as 1,200°F (650°C).

Key benefits of the Seal-Lok Xtreme fitting include resistance to over-tork tightening, vibration resistant, zero clearance (for easy plumbing), unlimited reusability, and reduced galling potential due to special dry film lubricated nuts.
The broad range of applications benefiting from Seal-Lok Xtreme’s rugged design

  • Combustion turbines
  • High-temperature engine compartments
  • Instrument panels
  • Chemical process equipment
  • LNG storage and fueling systems
  • Cryogenic equipment

"Applications such as liquid natural gas (LNG) and gas combustion turbines often pose challenges to a tube fitting’s elastomeric sealing," said Ted Amling, Senior Project Engineer, Parker Hannifin Tube Fittings Division. "Rather than using a standard sealing ring, Seal-Lok Xtreme fittings utilize a patent-pending metal sealing ring that improves sealing dependability against the severe temperature
