I'm trying to set-up a clawfoot tub supply on a bathroom reno. The water supply coming out of the concrete floor is 1/2" compression thread (male). The previous tub was 1/2" compression from the floor to 1/2" compression on the faucet with no shut offs. I want to install shutoffs on both the cold and hot lines, however, the nipple to the shutoff is 1/2" MIP. I'm having no luck locally finding a fitting that is 1/2" compression female on one end (to thread onto the floor supply) and 1/2" FIP on the other end (for my supply nipple to thread into before connecting the shut-off). Anyone know an online source for such a fitting?
