Question by: Ray R on Feb 23, 2026, 9:47 AM
got a 3/8 NPT male port on a pump housing and need to redirect the line at a right angle before connecting to a 1/2-20 SAE 45 flare fitting. this the right piece for that?
Answer by: Customer Support on Feb 25, 2026, 6:45 AM
That's what this adapter is built for. One end threads into your 3/8-18 NPT male port, and the other end connects to a 1/2-20 male SAE 45 degree flare. The 90 degree elbow body handles the direction change, so you're not fighting the line trying to make a hard bend somewhere downstream. It's brass construction, so it's a solid fit for most fluid system work where you need a clean right-angle transition between those two thread types.
