Psc inlet thread?

[Cracksrubi]

I’m trying to see if anyone knows the thread size of the inlet on the PSC CBR pumps it’s -12an male to some other kind of male. I just don’t know what the pump body is threaded.

Looks like an ORB (O-Ring Boss) fitting. They are typically standard threat pitches so measure the thread diameter and lookup what that thread size correlates to in sizing.

Yep, should be an ORB. Same type used for the rams.

That’s what I was thinking too but it’s like a really fine thread compared to the stuff I have in my extra fittings drawer. Their coarse and the female will fit on the an fitting and the orb for those if that makes sense

It’s not m18 or m22

It’s not 3/8 or 1/2
The British pipe thread was closest in overall diameter but thread pitch was all wrong
I suspect it’s m20x1.5 but cannot confirm

Hydraulic shop said it’s a 13/16 20 thread incase anyone else needs to know I’ve ordered the tap waiting to see if it all works out
