243 Helium Leak Detection Fixture

[@StuartsShed]

Ah! Now helium leak testing I know plenty about. 35 years of hands on experience of that and vacuum technology. 👍
Great stuff.

Thanks. I would love constructive criticism.

@@DudleyToolwright I think you took a very solid approach and made a nice fixture. I do have some suugestions and tips which I think will help push your fixture past 1.0 X 10-9 std cc He / s, but it’s easier to write in an email. So I’ll get that off to you asap. You’re on totally the right track though. 👍

Nitrile rubber has a lower helium permeation coefficient and would have been a better choice for gasket material than Viton . Viton would only be preferable if you were dealing with temperature extremes. As an added benefit, nitrile rubber gasket material is significantly less expensive and readily available.
A cheap diode laser can easily cut gaskets and you might be able to get one free for doing a review.

Thanks for the info. I found that out later. Initial searches all pointed towards Viton, which is a lot more expensive and much stiffer on the average. Nice tip on the laser. Thanks!

That was interesting.

Thanks, Tom. Lots to learn.
