Brass Adapter, 1/4 in Male SAE 45 deg Flare to 1/2 in Male NPT, Straight

That's what this adapter is built for. One end is 1/4 inch male SAE 45 degree flare, the other is 1/2 inch male NPT, and it runs straight through with no offset. Brass construction means it plays well with most fluid systems where those two thread types need to meet. As long as your flare connection is SAE 45 degree spec and your port is female 1/2 NPT, you're looking at a direct fit.
