1/8 inch NPT brass ball valves are compact and precision-engineered flow control devices designed for reliable shut-off in very small-diameter piping and instrumentation systems. Featuring NPT threaded connections, they provide secure, leak-resistant installation in tight or confined spaces. Manufactured from corrosion-resistant brass, these valves deliver dependable performance in low to medium pressure applications and are suitable for air, water, oil, and other non-corrosive fluids. Thanks to their miniature size and smooth quarter-turn operation, 1/8 inch NPT brass ball valves are commonly used in gauge lines, pneumatic systems, laboratory equipment, and small-scale fluid control applications.
