Rol-Air 132BV Mini Ball Valve 1/4 MNPT x 1/4 FNPT

Rolair 132BV Mini Ball Valve is a compact 1/4" MNPT x 1/4" FNPT shut-off valve engineered for use with Rolair air compressors and other pneumatic systems that employ 1/4" NPT connections. The valve functions as a drain cock and inline shut-off, enabling fast condensate drainage from the compressor tank or adjacent piping with a single quarter-turn of the handle. Its two 1/4" ports—one MNPT and one FNPT—let you thread it directly into standard Rolair fittings or 1/4" NPT assemblies, making installation straightforward in tight spaces. Designed for serviceability in shop and job-site environments, the 132BV is small enough to fit where larger valves won’t, yet it provides a reliable seal when closed to minimize leaks during operation. Typical applications include draining moisture from Rolair tanks, isolating a section of a pneumatic line for maintenance, or serving as a compact shut-off in portable air systems where space is at a premium. This model is sold as a dedicated replacement valve for Rolair equipment that uses 1/4" MNPT to 1/4" FNPT connections, ensuring compatibility with common 1/4" NPT hardware and fittings used in small to mid-size air compressors and pneumatic circuits.
