GRACO 237537 – Low Pressure Ball Valve, 3/8″ Tube Fitting Both Ends, Stainless Steel, Catalyst &

GRACO 237537 – Low Pressure Ball Valve Compatible w/ stainless steel, Catalyst & Waterborne Materials, 3/8″ OD Tube x 3/8″ OD Tube, 500 PSI

Professional-grade ball valve designed for finishing applications with stainless steel and PTFE construction, offering reliable flow control for catalyst, waterborne, and other finishing materials with multiple connection options to meet specific application needs

Features:

Use for on/off fluid control. Allows safer system operation by permitting relief of fluid pressure or isolation of components from pressure during maintenance. Ball vales must be used in the fully open or closed position. Do not throttle the valve – it could cause premature seal failure.

Stainless steel and PTFE materials are compatible with catalyst, waterborne, and other finishing materials

Many different connection options to meet your specific needs
