Question by: Gary B on Oct 24, 2025, 8:46 AM
got a bulkhead tee setup already, are all three ends on this one 9/16-18 male JIC 37 flare?
Answer by: Customer Support on Oct 26, 2025, 6:48 AM
All three connections are 9/16-18 male JIC 37 degree flare. It is a bulkhead branch tee, so you have one bulkhead branch plus a run and a branch, all in the same 9/16-18 JIC flare size.
Question by: Janet R on Oct 14, 2025, 9:54 PM
What kind of systems is this tee adapter actually built for? Like is it just hydraulic lines or can it handle other stuff too?
Answer by: Customer Support on Oct 16, 2025, 4:01 PM
Hydraulic is the main use, but it also works in instrumentation and chemical processing systems. The 37 degree JIC flare fitting style is common across all three of those applications, so the adapter handles more than just straight hydraulic lines. Just make sure your line connections match the 9/16-18 thread size on all three ports before you order.

Just want to make sure, this here is a tee fitting, right?
Answer by: Customer Support on Nov 25, 2025, 12:57 PM
That's right, this is a tee adapter, specifically a branch tee. It's got a 9/16-18 male JIC 37 degree flare bulkhead on the branch, and the run and branch both have 9/16-18 male JIC 37 degree flares.
