Question by: Janet S on Jul 18, 2025, 1:18 PM
got a tee fitting in my hand marked 203003-4-4S, is that the one that goes from a -4 SAE O-ring boss over to -4 JIC on the run
Answer by: Customer Support on Jul 20, 2025, 6:53 AM
What you’ve got there is an Eaton Aeroquip 203003 Series tee adapter that ties a 7/16-20 male SAE O-ring boss (straight thread O-ring) branch into a 7/16-20 male JIC 37 degree flare run. It’s essentially a -4 size tee that transitions between ORB and JIC in that configuration.
