Whitey® '40' Water Shut Off Valves

To manage water flow around a vacuum system, we recommend the Whitey® 40-series ball valves in brass and stainless steel. Choose the valves with Swagelok® fittings when connecting to stainless steel water tubing, and with NPT fittings when they will be connected to reinforced plastic tubing terminated in NPT hose connectors (see Hose Connectors).
