1) Where do you recommend to order custom 1/2" stainless tubes?
2) What is the best way to use the compression fittings shown to have the tubes connected, but not permanent? I would need to remove the tubes when I clean to remove the false bottom and hop stopper.
If I remember correctly, I once saw a place that sold them with o-rings, but I cannot remember where.
Need info for o-ring size to make tube non-permament
Here is what I think I need.(be sure to provide input if you have additional ideas)
I am working on making the pickup tubes removable. If I use the compression fitiings as they are meant to be used, the ferrules will dig into the tube and will not be able to be removed and used again.
So, by following Kal and his Ultimate Brewery design and instruction, I decided to just use o-rings.
He shows how this works on his chiller, but he uses 5/8 compression fittings and I am using 1/2 for pickup tubes. He uses the o-rings so the ferrules do not dig into the copper pipe, but this should work for my purpose as well.
Here are his photos that show what I am wanting to do.
This shows the way the compresiion fittings are made to be used.
Here is the way I want to use them with o-rings replacing the ferrule.
THIS IS WHERE I MAY NEED HELP.
Has anyone done this? Kal lists McMaster Carr part number 9396K24 for his o-rings for 5/8 compression.
I think I may need part number 9452K172 for 1/2 compression.
i as looking for this info again as well, i remember seeing it on some vendors sight. They had taken a 1/2" npt x 1/2" compression and drilled the compression side so the tubing slid all the way thru and sealed with o rings instead of the metal ferrule.
The ferrules may dig into the tube, but you can take out the dip tube and put it back into the compression fitting everyday for the next 20 years and never have an issue with it. Why would you want to replace the tube beyond just removing it for cleaning purposes?
If you order a pickup tube from Bargain Fittings they send you the ferrules for the compression fitting. They also send silicone o-rings so you can hook it up without the ferrules. If you use the ferrules you can still remove the dip tube. What's the big deal if the ferrules bite into the dip tube?
