Got a bulkhead pass-through with 3/4-16 JIC on both sides, is this the right straight adapter for that?
Answer by: Customer Support on Oct 30, 2025, 9:37 PM
For a straight bulkhead connection where you want male JIC 37 degree flare on both ends, this matches that setup. It is a steel 37 degree flare union adapter with 3/4-16 threads on each side.

got a bulkhead spot in a panel that needs a straight-through JIC connection on both sides, this gonna work for that?
Answer by: Customer Support on Nov 17, 2025, 7:04 AM
Both ends are 3/4-16 Male JIC 37 degree flare, so yes, it threads directly through a bulkhead panel and gives you a male JIC face on either side. The straight configuration keeps everything in line without any offset or angle, which makes it a clean fit for panel-mount hydraulic connections where space is tight and you need a secure pass-through. It's from Eaton Aeroquip's 2041 series, built for hydraulic, instrumentation, and chemical processing systems.
Question by: Cheryl C on Sep 27, 2025, 10:44 AM
Can this bulkhead adapter handle hydraulic systems, or is it just for instrumentation and stuff like that?
Answer by: Customer Support on Sep 29, 2025, 6:36 AM
It's made for hydraulic systems, instrumentation, and even chemical processing setups. So yeah, it'll definitely handle hydraulics.
