best pipe to avoid hydrogen gas leaks

[mithyl2]

when doing a reaction with sodium Borohydride and h2 gas evolves and is then directed through a pipe from the reaction vessel, is there a best material/type of pipe to use to make sure that no sodium Borohydride leaks happen? is silicone better than PVC?

Hydrogen is not corrosive in the common sense, any material will do. Its also not poisonous and will go up immediately so as long you have no candles burning under the ceiling why bother with a pipe, good ventilation will do.
