Copper, Brass and stainless in the brew pot?

Any issues? I mounted my weldless a bit high on my brew keg, so I need to have a drain tube and not sure where to get the foot of stainless and compression fitting I need.

Any ideas?

Any industrial fluid control products company would have that. Also, surprisingly you can find all of that on Amazon.com through smallparts . They have both items and in many cases it is cheaper than the local industrial place will sell to a walk in customer.

Amazon.com: Parker 8MSC8N-316-01 316 Stainless Steel A-LOK Male Connector 1/2" Compression Fitting 1/2" M NPT: Industrial & Scientific

$12.60 I just bought another one, locally I had paid $16 + for the same thing.

Also McMaster- Carr should have it, Grainger, etc. or a well stocked plumbing supply house.
