Anyone have a list of maximum safe pressure for different kinds of fittings? I used to have a general one that listed the different types of metals and maximum pressure. Cannot find it anywhere.
We have a customer that put a brass fitting on the end of a 5000psi gauge.
Anyone have any ideas?
For the most part I use the specs out of my MSC Industrial Suppy catalog. I don't know if it will help in your application, I use it to keep our lab techs from killing themselves.
I know I wouldn't be happy with brass at 5,000psi.
Try ANSI B.31
Grab a copy of the Swagelok catalog, they have some nice pressure tables and can be used as a general reference.
An example from their catalog lists pressure ratings (PSIG) for their NPT fittings and adapters as follows:
NPT Male Female Male Female
316SS Brass
1/8 10,000 6,500 5,000 3,200
1/4 8,000 6,600 4,000 3,300
