VMA422 connections

Hi! I wonder if someone now what size the thread are on Water valve VMA422.

Hello Goophster,

The “thread” is ½” BSP, which corresponds to a measured diameter of approximately 20 mm.

At product page on Our website, the specifications say “inlet-outlet 8mm ( 0.315" ).”, that is if You use the supplied couplers.

Hope to have informed you sufficiently

Best regards,
