Product Questions & Answers (2)

Question by: Clint S on Oct 4, 2025, 3:53 PM
what industries is this adapter actually used in? trying to figure out if it'd work for our setup before ordering
Answer by: Customer Support on Oct 6, 2025, 9:35 AM
Food and beverage processing, chemical processing, pulp and paper, marine and military applications, and offshore drilling are all listed uses for this adapter. It bridges a 1/4-18 female NPT port to a 1/2-20 female JIC 37 degree flare swivel, so anywhere you've got those two connection types that need to meet up in a straight run, this part fits right into that picture.
Question by: Todd F on Feb 13, 2026, 9:29 AM
got a hose end with 1/4-18 female NPT and i need to hook into a 1/2-20 JIC, is this the right adapter?
Answer by: Customer Support on Feb 15, 2026, 8:58 AM
It matches those exact thread callouts: one side is 1/4-18 female NPTF internal pipe, and the other side is 1/2-20 female JIC 37 degree flare swivel, straight through.
