Product Questions & Answers

got a bulkhead port and need to go from 3/8 pipe female over to a JIC flare, is this the right adapter?

Question by: Harold H on Oct 10, 2025, 11:08 AM

For a straight bulkhead setup, this adapter is a 3/8-18 female NPTF on one side and a 3/4-16 male JIC 37 degree flare on the other, so it matches that pipe to JIC flare changeover.

Will this bulkhead fitting hold up to typical hydraulic pressures in an off-road vehicle application?

Designed for demanding environments, this Eaton Aeroquip adapter is frequently used in marine, military, and off-shore drilling applications, suggesting it can handle substantial pressure.
