Specialty Mfr 6380990 Ball Valve 3/8 Inch Mnpt X Fnpt Pvc

Product Description

The SPECIALTY MFR 6380990 is a standard manual ball valve designed for 3/8-inch pipe connections in fluid control applications. It features a male NPT inlet and female NPT outlet configuration, a PVC body for corrosion resistance, and a Buna-N seal for reliable shutoff performance. The wedge-style handle allows for quick quarter-turn operation to open or close flow. This valve is suited for plumbing, irrigation, chemical handling, and light industrial systems where a durable, low-maintenance shutoff device is required. Installation and service are typically performed by licensed plumbers or qualified mechanical contractors.

This ball valve is commonly installed in residential and light commercial plumbing systems, pool and spa equipment lines, irrigation manifolds, and process piping where PVC construction is specified for corrosion resistance. The 3/8-inch MNPT x FNPT end connections allow it to thread directly into standard pipe fittings without additional adapters in most configurations. It is appropriate for cold and ambient-temperature fluid service within the pressure and temperature limits of PVC and Buna-N materials.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanic in accordance with applicable local plumbing codes and the IPC. Shut off system pressure and drain the line before removing or installing the valve. Use appropriate thread sealant on NPT connections and hand-tighten before applying wrench torque to avoid cracking the PVC body. Do not exceed the pressure and temperature ratings of PVC or Buna-N materials for the intended service fluid.
