got two 1/2-20 JIC male ends i need to join straight, is this the right kind of union?

For tying two male JIC 37 degree flare connections together inline, this is the right style. It is a straight union with 1/2-20 male JIC 37 degree flare on both ends, so it matches same size to same size.

Got two male JIC ends I need to tie together inline, both 1/2-20 thread. This the right piece for that?

That's what this fitting is built for. Both ends are 1/2-20 male JIC 37 degree flare, so it bridges two female JIC connections in a straight line without changing thread size or direction. It's a true union, same spec on both sides.

Question by: Terry K on Nov 2, 2025, 12:14 PM

So this is just a straight adapter, right? Both ends are the same size?

Correct, this stainless steel adapter is a straight union. It's designed to connect two 1/2-20 male JIC 37-degree flare connections in a straight line, and both ends have the same 1/2-20 thread size.
