3/8" M x 3/8" F BSP Closing Valve

3/8" BSP Ball Valve (Closing Valve)

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.
