H2-Fittings and Tubes

WEH® H2-fittings ensure the leak-free connection of pipe components. The cone and thread fittings are a simple and
reliable fitting system.
All fittings are supplied complete with the appropriate fittings.
WEH® H2-fittings are metal-to-metal sealed and can be screwed on again several times.
They are suitable for pressure ranges up to 1,379 bar / 20,000 psi.
Suitable for pipes in the standard market sizes 1/4“, 3/8”, 9/16”, 3/4“ and 1“.
Our fittings are available with both metric and imperial threads.
WEH® H2-fitting up to 1,379 bar / 20,000 psi are sealed with a 59° external cone at the pipe end and a 60° internal cone in
the fitting (medium pressure-fitting 60° Cone&Thread).
WEH offers all the necessary tools for applying and finishing the outer cone on the pipe ends and repairing the inner cones.

Applications
WEH® H2-fittings are specifically designed and tested for hydrogen applications.
The bodies of all fittings are made of special 316/316L alloys with controlled nickel, chromium, and molybdnum content.
This significantly reduces the risk of hydrogen embrittlement, thereby ensuring a longer service life.
Typical applications include hydrogen storage systems, compressor systems, and dispensers, as well as test systems for
hydrogen components.
