Rubber Seals for Hydrogen Applications
Hydrogen seals retain gas within mechanical systems, preventing oxidation and dangerous leaks. They ensure stable pressure and system integrity, which is vital for performance and safety—especially in fuel cells.
What is Hydrogen?
Hydrogen is a colourless, odourless, highly flammable and reactive gas. Used as an alternative to natural gas, it plays a crucial role in sustainable energy. Due to its small molecular size, it easily penetrates materials—even stainless steel—making sealing a major challenge.
Effects of Hydrogen Exposure
Long-term exposure to hydrogen environments can cause elastomeric seals to become brittle, crack, or tear. Swelling may impair mechanical and sealing performance. Discolouration and degradation are also common.
At Power Rubber, we supply high-performance rubber compounds with low gas permeability and strong resistance to chemicals and heat.
Choosing the Right Material for Hydrogen Seals
Our hydrogen-compatible rubber seals are manufactured using advanced materials that minimise gas permeation and ensure leak-free performance in both gaseous and liquid hydrogen applications. All materials are tested to meet stringent standards.
Industrial Use of Hydrogen-Resistant Seals
Our seals are widely used in aerospace, automotive, oil & gas, marine, energy, petrochemical, semiconductor, and hydrogen production industries.
Benefits of Hydrogen-Resistant Sealing Solutions

Why Hydrogen Seals Improve Safety
Hydrogen ignites faster and easier than petrol or diesel—and often burns with an invisible flame. Quality seals reduce fire and explosion risks and protect systems from hydrogen-related damage like corrosion.
