Trying to tie two JIC lines together, is this the straight union that’s male JIC on both ends?
Answer by: Customer Support on Feb 2, 2026, 9:14 PM
For joining two JIC 37 degree flare connections in a straight run, this adapter is a steel union with male SAE 37 degree (JIC) ends on both sides. Both ends are 1-1/16-12 thread, so it is meant for matching JIC female flare fittings with that same thread.

i’ve got two lines that are both 1-1/16-12 JIC, is this just a straight union to tie em together?

For joining two same-size JIC flare connections, this is the straight union style adapter. It has a 1-1/16-12 male JIC 37 degree flare on both ends, so it’s meant to connect two matching female JIC 37 degree flare fittings.
