Stainless Steel Adapter, 1/2-20 Male JIC 37 deg Flare Cap

Fit comes down to the thread and flare style. This cap is a 1/2-20 Male JIC 37 degree flare cap, so it matches a 1/2-20 JIC 37 degree connection.

It comes with a 1/2-20 thread size.

JIC 37 degree flare fittings seal at the flare angle itself rather than relying on a separate gasket or O-ring. This cap threads onto a 1/2-20 male JIC fitting and closes off the end of it, which is handy when you need to block a port temporarily or cap off a line that's not in use. The stainless steel construction holds up well in environments where corrosion is a concern.
