Ed,
That's way too dear, you should be able to get them for about $10 US ea. I
must admit I had to shop around as well. The ones I ended up with weren't as
perfectly finished as the expensive one but the same material 316SS.
Our design has an inner cooling tube and an outer cooling tube and heat
shield, all the ends are cones as well!
All I have to do is get my welder to finish it.

Sounds like the right formula, George - will wait for your project's

outcome

before I try cones.  Yes, I did find some cone  inserts at $60.00 USD

each.

I would need 4 for my two tubes - hummm makes one tube sound better all

the

time.
