For tying two same-size JIC flare ends together in a straight run, this adapter fits that job. It is a 2027 Series union with 1/2-20 male JIC 37 degree flare on both sides.

Will this fitting work for hooking up hydraulic lines on my tractor?
Answer by: Customer Support on Jun 25, 2025, 6:04 AM
This adapter is designed to connect two SAE 37-degree flare fittings of the same size, so if your tractor uses that type of connection, it should work fine.
