Product Questions & Answers

fitting's got a 1/4-18 male NPT on one end -- what's the thread setup on the other side?
Question by: Keith H on Oct 18, 2025, 11:24 AM
The other end is a 0.31 inch female 42 degree inverted flare. So you've got a female inverted flare on one side accepting a matching flare fitting, and a male NPT thread on the other end that screws into a standard pipe thread port. Straight configuration, no angle to it.

got a line with a 5/16 inverted flare female end and i need to tie into a 1/4 npt port, is this the right little adapter?
Question by: Denise M on Jan 27, 2026, 8:41 PM
For that mix of ends, yes. This adapter is a straight brass fitting with a 0.31 inch (5/16) female 42 degree inverted flare on one side and a 1/4-18 male NPT on the other, made for a secure, leak resistant connection between those two styles.
