Male Metric X Female Bspp

The opposite end carries a G 1/2-14 female BSPP connection. So if your existing line or component has a male BSPP half-inch fitting, this adapter bridges straight across from that Metric M18 x 1.5 male side to it. Both thread types and sizes are fixed, there's no adjustability on either end, so just confirm your mating hardware matches those two callouts before ordering.

It bridges those two thread standards in a straight steel fitting, with an M18 x 1.5 male on one end and a G 1/2 - 14 female BSPP on the other.
