These are much nicer tubes for about the same price. They come with a three pack of micron screens and a clamp. The one you linked to those are all extra.

I would not get anything cheaper or smaller than the provac you linked to. It's a great starter chamber and a good value.

That pump is not ideal. It is rated at 500u. Not enough for proper extracts. You really don't want to skimp out on the vac. It's extremely important to ensure properly purged oil. IMHO the minimum you want to be looking at is the Robinair 15300 but if it were me I'd spend a couple extra bucks and get the Robinair 15500. I own the 15550 and it works great! It's also probably the best value on the market right now at the price amazon is selling them.

I'd also advise picking up a roll of Oil Slick Sheet. You can blast right on to it. It works well for small runs.

As far as your tek, watch this video and do it just like shown and you'll be golden!

Its a bit pricier but for holding a deep vac on a 5 gallon ive never had a robinair fail me.

What is your elevation also? Neat perfect vacuum is hard to achieve much over sea level.
