Question by: Duane B on Apr 23, 2025, 6:26 PM
what's the port size on this coupling and will it thread into a standard NPTF fitting?
Answer by: Customer Support on Apr 25, 2025, 6:55 AM
The port connection on the female half is 1/8 inch NPTF, so yes, it'll thread directly into any standard NPTF-tapped port without adapters. The overall end sizing runs 5/16 inch on one end and 1/8 inch on the other, and the thread-to-connect internal design means no special tools are needed to get it seated properly.
