Product Questions & Answers

what's the difference between NPTF and NPSM on this thing, and does it matter which end goes where when I'm putting it in?

Question by: Connie H on Jan 19, 2026, 10:01 AM

Both ends on this adapter are male, but they use different thread standards. NPTF threads are tapered and form a pressure-tight mechanical seal on their own when tightened correctly, which is why they're common in hydraulic and pneumatic lines where you can't afford a weep. The NPSM end uses straight threads and typically relies on a mating fitting or sealant to hold pressure. Neither end is interchangeable with the other, so orientation matters depending on what you're connecting to. Match the NPTF end to a female NPTF port and the NPSM end to its corresponding female NPSM fitting and you'll have a proper connection on both sides.
