got two lines that are both 1/2-20 SAE 45 flare male, will this union join em up straight?
Answer by: Customer Support on Feb 19, 2026, 4:38 PM
Built for exactly that situation, it’s a straight flare union with 1/2-20 male SAE 45 degree flare ends on both sides, so it connects two matching 45 degree flare fittings together in-line.

both ends on this thing are male SAE 45 flare, right? just want to make sure before i order, trying to union two male fittings together on a power steering line
Answer by: Customer Support on Dec 18, 2025, 6:30 AM
both ends are 1/2-20 Male SAE 45-degree flare, so it works as a union between two male fittings on the same size line. That makes it the right pick when you've got two male-terminated lines that need to meet in the middle without adapting to a different thread or flare type.
