Question by: Dale J on May 18, 2025, 6:55 PM
got a 3/8 male NPT line coming off a pump and need to step it down to a 1/4 female port on a valve block, this elbow gonna work for that?
Answer by: Customer Support on May 20, 2025, 6:45 AM
That's exactly what this fitting handles. The male end is 3/8-18 NPT and the female end is 1/4-18 NPT, so you're stepping down the thread size while also making a 90-degree turn. Both ends are NPTF, which gives you a dry-seal connection without relying solely on tape or compound to stop leaks. For a pump-to-valve block setup where space is tight, the elbow orientation saves you from needing a separate street elbow and a reducer.
