Over the years, I have used them all, but personally prefer the red india rubber sold by many vacuum dealers. It will not collapse as they sell it only in wall thicknesses which will not allow that to happen, based on bore and outer diameter. Early on I used the heavy black threaded auto water hose. It never collapsed. For a long time I used the steel internal coil steel reinforced tubing, but in 2004 switched to the red rubber. (I have seen it in white as well).....As always on the fore line try and keep the line under 1 foot long. Fusor V uses an 8-inch length of the red rubber from Duniway.

Re: Restarting Efforts on Demo Fusor II
All puchased components are in hand and I finally had some time to put it all together and do an initial vacuum test (without the HV feedthrough).
I was able pump the chamber down to 20 mTorr in about 15 minutes.
Next up is to mount the HV Feedthough on the empty 6 in blank.
