PTF-SAE Short Thread

[izzy123]

Is a PTF-SAE Short thread the same as an NPT thread, but a dry seal variation? We are in a mechanical/hydraulics industry and we constantly use NPT, UNO, BSPP and BSPT threads but have not come across PTF-SAE short. I was wondering if they are compatable (ie: can you screw a PTF-SAE short male thread into an NPT female thread?).
