Thanks Rich. I also need to work out the details on the o-ring grooves.
Also the inner diameter can be a bit less where the tubes go in as I think
1 3/8 inch OD tube with an .049 wall might be plenty big and strong enough
for water plumbing. We are going to think that through before we commit
to 200. We could always bore them out to fit the tube of our choice.

I was looking at the grooves. I don't like the square corners in the
grooves & would like to make it with a radius. This will add strength.
What do you think?
Also is the wall from the ID to the bottom of the O-ring groove too
thin?
Rich
Yes on the wall being too thin. I think 1.25 inch ID is about right.
The grooves have to be made very carefully or the O-rings will
not work. More on this next week as I am obtaining a catalog of
O-rings with a drawing of the proper groove dimensions.
