trying to replace an elbow adapter i’ve got. is this the one that goes from 1/8-27 npt to 7/16-20 jic flare?

Match the threads and ends and you are in the right neighborhood. One side is 1/8-27 male NPTF pipe thread, and the other side is 7/16-20 male SAE 37 degree (JIC) flare, built as a 90 degree elbow.

What's the A and B dimension on this elbow? Just need to make sure it'll fit in the space I got.
Answer by: Customer Support on Jan 23, 2026, 6:28 AM
The "A" dimension, which I believe refers to one side of the elbow, is 0.78 inches. The "B" dimension, likely the other side, is 0.89 inches.

Got a line running from a 1/8 NPT port and need to redirect it to a JIC fitting without a bunch of inline pieces. this adapter do that in one shot?
Answer by: Customer Support on Aug 22, 2025, 6:29 AM
One fitting handles both the thread conversion and the direction change. The male 1/8-27 NPT end threads into your pipe port, and the male 7/16-20 JIC 37-degree flare end connects to your JIC line. The 90-degree elbow geometry means you can route away from tight clearances without stacking extra adapters in the line.

trying to hook up a 1/8 pipe port to a 7/16-20 jic line, is this the right elbow for that?
Answer by: Customer Support on Mar 6, 2026, 2:17 PM
For that kind of hookup, you want an adapter that goes from 1/8-27 male NPT on one end to 7/16-20 male JIC with a 37 degree flare on the other, and in a 90 degree elbow. That is exactly what this 2024-2-4S is.
