3/8 BSP Male x 3/8 Compression Male

3/8" BSP Male x 3/8" Compression Male Adapter

The fitting you need to connect a European espresso machine's BSPP water inlet to standard American compression plumbing. Machined by Espresso Parts in the USA from 303 stainless steel specifically to bridge this thread mismatch.

SPECIFICATIONS

PRO TIPS

• The confusion this fitting solves: 3/8" BSPP measures roughly 5/8" (~16.5 mm) across and will NOT thread onto NPT fittings despite both being called "3/8 inch", trying to force them is the most common water-line install mistake we see. Background on BSPP threading is available here.
