Q&A
Q: MS28778-12 says its 3/4 on your site. Other sites show closer to 1, and that is the correct size for my application Can you verify the actual size? Original P/N is AN6290-12.
It is closer to 1". The 3/4 is in reference to what size AN fitting it is used with. An AN815-12 for example is a 3/4 fitting but measures almost an inch in diameter.
