Just trying to figure out what fittings to get for my TSS2021 and ZK1 unloader. I read that they both use BSTP threads, but I see no pressure washing stores actually selling fittings that aren’t NPT.
Are the fittings compatible? I have read they absolutely aren’t.
Are the ZK1’s and General Pump pump’s sold with NPT threads on the US market?
I see guys screw quick connects right into the outbound on the GPs so I’m guessing they must be NPT?
