Male Orfs X Male Bspp

That's what this one's built for. One end is a 1-inch Male ORFS with a 1-7/16-12 UN thread, and the other is a 1-inch Male BSPP with a G 1-11 thread. If your ORFS line and your BSPP port are both 1-inch, this straight steel fitting connects them directly with no additional hardware needed.

For tying those two thread styles together, this fitting is a straight steel adapter with a male ORFS on one end and a male BSPP on the other. Both ends are 1 inch, with a 1-7/16 - 12 UN callout on the ORFS side and a G 1 - 11 callout on the BSPP side.

This fitting is designed with a Male BSPP (British Standard Parallel Pipe) connection on one side, which should be compatible with standard BSPP threads. The specific callout for that side is G 1 - 11.
