A 3/8″ male BSP x 3/8″ female BSP ball valve, the most common shutoff valve configuration used in espresso machine plumbing, with a quarter-turn lever handle for quick on/off control.
SPECIFICATIONS
- 3/8″ male BSP x 3/8″ female BSP
- Quarter-turn ball valve with lever handle
COMPATIBILITY
- Fits: general espresso machine plumbing using 3/8″ BSP shutoff valves, including La San Marco machines
- Replaces: also see V_531 or SM_527 for the 1/4″ configuration
INSTALLATION
A simple DIY swap, hand-thread and snug with a wrench, confirming the handle has full quarter-turn travel once installed.
PRO TIPS
- Double-check this against your parts diagram before ordering, this exact valve is listed incorrectly on some La San Marco exploded diagrams, so match by thread size and gender (3/8″ M x 3/8″ F) rather than by diagram part callout alone.
