ORB O-ring size?

Does anyone know the O-ring size specified for an AN-4 ORB fitting. I have the old one and it looks like 3/8 X 1/2 X 1/16. However it is a bit deformed and I think that I am getting a thickness of .077". A bit surprised as that would be a non-standard size.

EDIT: Disregard, I found it.

ORB O-ring Size

If it is for a port defined by SAE J1926, these are a special series of o-rings. For a tube OD of 1/4" or a thread size of 7/16"-20 the o-ring size is 3-904. W width is 0.072", ID is 0.351".
