Question by: Diane C on Aug 9, 2025, 2:47 PM
got a port i need to cap off, is this the right kind of plug for an inverted flare seat?
Answer by: Customer Support on Aug 10, 2025, 6:38 PM
For an inverted flare connection, it’s meant to seal on a 42 degree inverted flare seat with a 0.31 inch male inverted flare plug end. It also uses a 0.5 inch UNF thread, and it’s built to make a secure seal without needing added thread sealant.
Question by: Dale M on Nov 17, 2025, 7:35 AM
Does this plug need any thread sealant or tape to make a good seal, or does the flare angle take care of that?
Answer by: Customer Support on Nov 18, 2025, 8:41 PM
The 42 degree inverted flare design handles the sealing on its own. No thread sealant or tape is needed to get a secure connection. That flare geometry creates the metal-to-metal seal, so adding sealant would actually be unnecessary and could interfere with the fit.
