what industries is this adapter actually built for? trying to figure out if it'd hold up in our processing setup

Marine, military, chemical processing, pulp and paper, food and beverage, and offshore drilling are all listed applications for this adapter. That covers a pretty wide range of demanding environments, so a general industrial processing setup fits right in with what this part was made to handle.

got a hose end with a 7/16-20 jic swivel on it. is this the little adapter that’ll go into a 1/8 pipe port?
Answer by: Customer Support on Apr 24, 2025, 1:16 PM
Matches that setup. It’s a straight steel adapter with a 1/8-27 male NPT pipe thread on one side and a 7/16-20 female JIC 37 degree flare swivel on the other.
