Seal-Lok Xtreme Fitting for Extreme Temperatures
Parker Hannifin
All around the world, the cost of turbine downtime is a critical issue. Parker has created Seal-Lok Xtreme, a robust, leak-free connection that addresses the need for reliable fuel connections in extreme-temperature applications. An industry necessity, it utilizes a patented metal seal to extend the temperature capabilities of the industrial standard O-ring face seal design to an impressive range of -328°F (-200°C) to 1200°F (650°C). Proven benefits of this design are its resistance to over-tightening, zero clearance assembly, unlimited reusability, ease of assembly and vibration resistance, making Seal-Lok Xtreme an ideal solution for power-generation applications.  Visit our blog.

“Applications such as liquid natural gas (LNG) and gas combustion turbines often pose challenges to a tube fitting’s elastomeric sealing. Rather than using a standard sealing ring, Seal-Lok Xtreme fittings utilize a patented metal sealing ring that improves sealing dependability against the severe temperature or chemical compatibility issues that reduce the life of elastomeric seals.”
