trying to hook a pipe port to a JIC hose end, is this the straight adapter for that
Answer by: Customer Support on Dec 19, 2025, 6:11 AM
For tying a male NPTF pipe thread to a male SAE 37 degree JIC flare connection, this adapter is the straight pipe to 37 degree flare style. One end is 1-1/2-11-1/2 male NPTF and the other is 1-5/8-12 male JIC 37 degree flare.

Answer by: Customer Support on Jun 23, 2025, 3:08 PM
Match-up wise, that’s exactly what this adapter is. It’s a straight steel adapter with a 1-1/2-11-1/2 male NPT on one end and a 1-5/8-12 male JIC 37 degree flare on the other.

What industries is this adapter actually built for? Got a food processing line and want to make sure it ain't gonna be a problem using it there.
Answer by: Customer Support on Jul 10, 2025, 6:18 AM
Food and beverage processing is one of the listed application areas for this adapter, so you're in good shape on that front. It also covers marine and military use, chemical processing, pulp and paper, and offshore drilling. That's a pretty wide range, which speaks to how versatile the Eaton Aeroquip 2021 Series tends to be in industrial environments.
