Foster SV Series Couplers

Foster SV Series Safety Vent pneumatic couplers with Industrial Interchange and a zero-pressure connect/disconnect design that vents trapped air before the plug releases — preventing dangerous hose whip. Rated 300 PSI, one-way shut-off, and silicone-free for paint and powder-coat shops. Bodies from 1/4" to 3/4", including SVPC protective-cover versions. Steel construction; mates with standard Foster Industrial plugs.
