Product Questions & Answers (2)

Question by: Curt K on Nov 25, 2025, 1:05 PM
Trying to hook a 1 inch pipe thread line into a JIC flare hose, is this the right adapter?
Answer by: Customer Support on Nov 27, 2025, 6:42 AM
For that kind of hookup, it matches a 1 inch male NPTF end with 1-11-1/2 threads to a female JIC 37 degree flare swivel with 1-5/16-12 threads, in a straight adapter style.
Question by: Judy E on Jan 20, 2026, 5:18 PM
what industries is this adapter typically used in, and is it built for anything beyond standard shop work?
Answer by: Customer Support on Jan 22, 2026, 11:17 AM
Quite a few demanding sectors rely on this fitting. The listed applications cover marine and military use, chemical processing, pulp and paper use, food and beverage processing, and offshore drilling. That's a pretty wide range, and it tells you this adapter is meant for more than light-duty shop setups. If your operation falls into any of those categories, it's well suited for the environment.
