Description & Features

Designed for tight-space routing in demanding industrial environments, the Steel Adapter, 7/16-20 Male JIC 37 deg Flare To 7/16-20 Male JIC 37 deg Flare, 90 deg Elbow Bulkhead is a same-size JIC-to-JIC 90-degree bulkhead fitting from Eaton Aeroquip's 2043 Series. The 37-degree flare seating on both ends provides a reliable metal-to-metal seal suited to high-pressure hydraulic circuits where leak integrity is critical.

Question by: Gary H on Jul 27, 2025, 7:37 PM
Got a bulkhead setup on a piece of offshore equipment and need a 90 degree JIC elbow that'll hold up in saltwater conditions. this one rated for that kind of environment?
Answer by: Customer Support on Jul 29, 2025, 6:51 AM
Marine applications are actually one of the listed use cases for this fitting, so saltwater and offshore environments are right in its wheelhouse. It's a steel 7/16-20 male JIC 37 degree flare on both ends, configured as a 90 degree elbow with bulkhead mounting. The Eaton Aeroquip 2043 series is what you're looking at, catalog number C1AY54, and it carries dimension specs of 1.59 on the A measurement and 0.92 on the B measurement if you're checking clearances before you commit.

i got a tight spot on a bulkhead and need to turn the line 90, is this the right kinda elbow for that
Answer by: Customer Support on Jul 15, 2025, 6:47 AM
Built as a 90 degree bulkhead elbow, it’s meant for situations where you need the connection to pass through a bulkhead and then turn the line. Both ends are 7/16-20 male JIC 37 degree flare, so it’s a straight JIC flare to JIC flare connection with that 90 degree bend.
Question by: Judy F on Mar 15, 2026, 1:26 PM
Will this bulkhead fitting hold up okay in a marine environment?
Answer by: Customer Support on Mar 16, 2026, 5:06 PM
This Eaton Aeroquip adapter is suitable for marine applications, so it should work well for you. It's also used in chemical processing and offshore drilling, where corrosion resistance is important.
