Question by: Wayne R on Feb 10, 2026, 9:17 AM
Been looking for a bulkhead elbow to tie into a line on our offshore drilling rig setup. This the right kind of fitting for that application?
Answer by: Customer Support on Feb 11, 2026, 9:37 PM
Offshore drilling is one of the listed applications for this fitting, so you're on the right track. It's a 45 degree elbow bulkhead adapter with 1-5/16-12 Male JIC 37 degree flare on both ends, part of the Eaton Aeroquip 2042 Series. The bulkhead design lets it pass through a panel or wall, and the 45 degree angle helps route lines where a straight adapter just won't clear. Both ends are the same thread and flare spec, so your JIC connections on each side need to match that 1-5/16-12 sizing.

So this is a 45 degree angle, right? Just want to make sure before I order.

That's correct. This adapter features a 45-degree elbow design.
