Product Questions & Answers (1)

Question by: Cindy W on Dec 21, 2025, 3:47 PM
got a 1-inch NPT male fitting on a hydraulic line and need to step it down to a 3/8 female port, this bushing style adapter do that?
Answer by: Customer Support on Dec 23, 2025, 6:41 AM
That's what this one's built for. The male end threads into a 1-11/2 NPT port and the female end accepts a 3/8-18 NPT fitting, so you're reducing from a 1-inch male connection down to a 3/8-inch female. Bushing-style adapters like this screw directly into the larger port without needing a separate union or connector in between, which keeps the hydraulic connections tighter and cleaner.
