Anyone know what these fittings are called? I know they are -10 and -6 AN on one end but the other end is not an inverted flare and they use a rubber gasket / washer to seal against the reservoir body.

Looks like a bulkhead fitting without the nut.

It's not though because it uses a rubber gasket / washer.

It's called an o-ring AN fitting.

It threads into a female straight thread and uses an o-ring to seal. You can see the countersunk area on the tank where the o-ring seals. The other end is typical flared/AN.

In the hydraulic industry we call them UNO fittings - Aeroflow call them ORB fittings - you can get 90*, 45* and straights to male flare adapters as well as NPT. Generally they don't leak providing they are done up tight. No thread tape or sealant required - the o ring seats on a tapered seal area.

Thank you guys. The ones that come with the PSC reservoir are made in China and they leak. I want to change them to a better quality fitting. But I didn't know what they were called. Thanks again for your help.

Late to the party but my updated alcohol compatible fuel system uses these exclusively. I find them more reliable than NPT and thread seal.

You can buy one-Zs, two-Zs from these guys, shop online.

Here are the port adapters you were looking asking about.

You can also shop the Earl's part numbers at Summit and Jegs if you'd rather.

Best,
Kelly

Went back and read your first post. Do you have a close up picture of the female port?

There are number of variations on the female ports. The two basic styles are both three sided contact on the O--ring but one is a triangular gland and the other a square gland.

There is a third version that's really not a version at all and that is what I have seen on many of the import equipment. On those, there is not really any o-ring gland and it just smashes the o-ring in an interference fit like a gasket whereas the other two proper ports compress the o-ring to fill a percentage of the gland and the o-ring is actually a pressure activated seal that can deform in the gland and seals better with increasing pressure.

You can tell difference in ports by appearance and also because in the absence the proper gland, when you remove the fitting the o-ring is usually cut or badly & permanently deformed and cannot be reused. If this is the case, aside from machining the ports, I think you're stuck and buying a new male fitting wont do anything for you. Aside from machining the ports, the best you can do there is buy a new high durometer o-ring, lube it when you assemble, and don't overtighten it.

I cant tell for certain but the picture you posted looks like a proper female port. Is that what your actual ports look like? Good luck.

Best,
Kelly
