Plumber cannot find a 90° adapter with 3/8" straight (non-tapered) threading to connect a faucet supply riser to a faucet with integrated hoses.

Existing 90° connectors are only available in NPT tapered thread, not the straight (MIP/FIP/comp) thread needed, and search terms do not differentiate thread types effectively.
