MSS Type A Stub Ends:

[Outlaw500]

When writing a specification for a MSS type A stub end.

What is the correct specification that meets ASME code compliance?

The only specification I have been able to find is:

For example:

4" MSS Type A stub end Sch 40, Matl 304L, MSS-SP-43.

Shouldn't I also specify the SA number like SA-240?

Thanks

Agreed, SA-403 most likely.
