The 1/4 in. Female x Female Mini Ball Valve, Screwdriver, with Viton Seals (#46935LS) is a compact brass mini ball valve with Viton (FKM) seals for superior chemical resistance compared to standard Buna-N elastomers. Viton seals are compatible with hydrocarbons, chlorinated solvents, aromatic compounds, and many acids — making this valve the go-to choice for chemical metering pump installations, chemical injection skids, and aggressive-media shutoff applications.
