These are not NPT thread. They're more of a straight thread. But they're also not totally straight, so just maybe a poorly made straight thread. They're incredibly cheaply made. Don't use these. There's also barely any barb thread for making a connection so these would likely blow out under any real pressure. I won't be using them, but it's too late to return them. Seller refused to take a return for them.
