Product Questions & Answers

got a JIS 30 degree flare line that’s 3/8 tube OD, is this just a straight union to tie two male ends together?

Question by: Shawn W on Dec 20, 2025, 10:58 AM

For joining two JIS 30 degree flare connections in a straight run, this part is a male JIS to male JIS steel adapter sized for 0.38 inch tube outside diameter on both ends.

Does this adapter need any thread sealant to get a good seal, or does the JIS flare handle that on its own?

Question by: Stan M on Mar 1, 2026, 7:11 PM

The 30-degree flare geometry on both ends handles the sealing without thread sealant. That metal-to-metal flare contact is what creates the leak-proof connection, so you don't need to wrap it or coat it before running your lines.

Hey, will this here fitting work with standard JIS stuff without any sealant?

Question by: Vince F on Apr 22, 2025, 7:49 PM

That's right, this steel adapter is designed for a secure, leak-proof fit within systems using JIS 30-degree flare fittings, and it doesn't need any thread sealant.
