With the appropriate adapter, you can connect the line to any vacuum system and do it yourself very quickly. I have a Pfeiffer HiCube combination turbo pump and backing pump that I use now, but in the past, I've used a diffusion pump system or anything that someone will let me use for a few hours.

Subject: AMMRL: liquid He transfer line
Hi all,
Our liquid helium transfer line is losing the vacuum. Is there any vendor where we can re-vacuum it? Thank you very much.
