I need a bulkhead fitting for a hydraulic setup, and this looks promising. What exactly is this fitting made of?
Answer by: Customer Support on Feb 2, 2026, 7:33 AM
It's a straight steel fitting, so you can count on it holding up well in most hydraulic applications.

trying to swap a bulkhead fitting, what threads are on each end of this 2706-08-06?
Answer by: Customer Support on Aug 4, 2025, 6:01 PM
On the NPTF side it has a 1/2-14 male NPTF thread built to SAE J476, and the other end is a 9/16-18 male JIC 37 degree flare thread per SAE J514.

what's the thread setup on this bulkhead fitting, the NPTF side and the JIC side both?
Answer by: Customer Support on Jan 30, 2026, 9:20 AM
One end runs a 1/2-14 male NPTF thread, which meets SAE J476. The other end is a 9/16-18 male JIC 37-degree flare, built to SAE J514. So you've got two different thread types on a single straight fitting, which is pretty common when you're routing a line through a panel or bulkhead and need to transition between those two standards at the same time.
