Question by: Roy C on Nov 2, 2025, 2:48 PM

got a tight spot on a line, is this the elbow that steps down from 1/4 NPT to 1/8 NPT?

Answer by: Customer Support on Nov 4, 2025, 10:47 AM

For a right-angle turn with a size reduction, this one fits that job. It is a 90 degree steel elbow with 1/4-18 female NPT on one end and 1/8-27 female NPT on the other.
