When using high pressure BSPP fittings either bottom or top seals are needed. If on top, the fitting will have a flange under which a sealing ring or washer is often used, They can be soft copper, teflon , aluminum or a Dowty seal. Some other BSPP threads seal in the threaded hole like for pressure gauges. They can be also be made of various materials, but it is those I want to buy. What are they called?

Thank you Scotty and rc4fun. These are so common, yet very difficult to search for. Yes, I know they are simply a washer, but they are special, yet it appears they do not have a unique name. In the end, I ordered these from Scotty's ad, but I still do not know their correct name.

Do the search yourself. I have used all the names I could think of on multiple search engines with no avail. In the past, I have had to make them myself. I have made these from many plastics including Delrin and HDPE, but nothing works as well as Teflon because of gasket creep. Over time more torque at the fitting is required to stop leaks.

I with you Steve, I had a hard time finding them, search-wise. I think I searched PCP seals on the great Amazonia.
