Hydrogen

In hydrogen applications, the integrity of gas joint connections is essential for ensuring both safety and performance. High pressure, extreme temperatures, and chemical reactivity require specialized lubrication solutions.
Samaro, official distributor of Chemours' KRYTOX® lubricants, offers high-performance greases designed to deliver long-lasting sealing for threaded fittings, valves, and other critical gas handling components.

Proven technology for critical environments

The KRYTOX® lubricants offered by Samaro are BAM-approved (Federal Institute for Materials Research and Testing – Germany) and qualified by Air Liquide for use in industrial gas systems, including hydrogen and oxygen service.

These gas joint connection greases provide:

• Exceptional sealing performance, even under high pressure
• Total chemical compatibility with reactive gases such as hydrogen (H₂) and oxygen (O₂)
• No VOCs, no hydrocarbons, no silicones
• No auto-ignition temperature – safe for oxygen service
• Direct reapplication, unlike PTFE tape, which must be removed before reuse
• Broad material compatibility with PTFE, EPDM, FKM, and more

Typical applications in hydrogen systems

These greases for gas joint connections are commonly used in:

• Threaded fittings and gas connectors in high-pressure hydrogen circuits
• Valves, regulators, check valves, and flow control systems
• Hydrogen storage, distribution, and refueling infrastructure
• Fuel cells, electrolyzers, and H₂ production equipment
