Will this here fitting hold up alright in a hydraulic system pushing around 5500 psi?
Answer by: Customer Support on Apr 2, 2026, 7:24 PM
Designed to handle dynamic pressures up to 6000 psi, this adapter should work fine in your system at 5500 psi, giving you a bit of headroom.
Question by: Peggy P on Feb 3, 2026, 6:52 AM
trying to tie a JIC 37 degree flare line into an ORB port, is that what this 06MJ-06MORB straight piece is for?
Answer by: Customer Support on Feb 4, 2026, 8:57 PM
Built as a straight adapter, it bridges a male JIC SAE 37 degree flare on one end to a male SAE O-ring boss on the other. Both sides are SAE J514 with 9/16-18 threads, and it uses an NBR O-ring seal on the ORB side to help keep the connection leak-free.
