Product Questions & Answers

what industries is this adapter actually used in? trying to figure out if it'd work for our setup before i order
Question by: Lee J on Dec 27, 2025, 8:32 PM
Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this fitting. It covers a pretty wide range of demanding environments, so if your operation falls into any of those categories, you're in good shape. The 3/8-18 female NPT swivel on one end connects to a 9/16-18 male SAE O-ring boss on the other, straight through, no angle.

For that setup, this adapter matches a 3/8-18 female NPT swivel on one side and a 9/16-18 male SAE O-ring boss (straight thread O-ring) on the other, in a straight configuration.
