Value Collection 9938021085 Miniature Ball Valve 3/8 in

Product Description

The VALUE COLLECTION 9938021085 is a miniature manual ball valve designed for 3/8-inch pipe connections in small-diameter fluid control applications. The valve features a male NPT inlet and female NPT outlet, allowing straightforward inline installation without additional adapters in most configurations. The body and trim are brass construction with a chrome-plated finish, providing corrosion resistance in water, air, and light fluid service. The seat is polytetrafluoroethylene (PTFE) and the seal is NBR (nitrile rubber), a common combination for general-purpose shutoff duty. A wedge-style handle allows positive open and closed positioning with a quarter-turn operation. Licensed plumbers and pipefitters install this type of valve in tight-space service lines where a full-size ball valve would not fit.

This miniature ball valve is suited for residential and light commercial plumbing, HVAC condensate lines, compressed air service, and instrumentation supply lines where 3/8-inch NPT connections are specified. The compact envelope — 1.62 inches in length, 1.05 inches in width, and 1.87 inches in height — makes it practical for manifold assemblies, equipment panels, and under-counter installations where clearance is limited. The MNPT x FNPT end configuration threads directly into standard NPT-tapped fittings and port bodies.

Key Features

• 3/8-inch pipe size with MNPT x FNPT end connections for direct inline installation
• Brass body and trim for corrosion resistance in water and air service
• PTFE seat provides low-friction sealing and chemical compatibility with common fluids
• NBR seal material suited for water, air, and light petroleum-based media
• Chrome-plated finish adds surface protection in exposed or humid environments
• Wedge-style handle gives clear open and closed indication with quarter-turn operation
• Compact dimensions allow installation in confined spaces and panel assemblies

Compatibility

Designed as an OEM-style replacement or new-installation miniature ball valve for 3/8-inch NPT piping systems in plumbing, HVAC, and light industrial service applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off system pressure and depressurize the line before threading or removing any valve. Apply thread sealant tape or pipe dope to the male NPT threads per standard practice — do not overtighten, as brass bodies can crack under excessive torque. Verify that the fluid media and operating pressure are within the rated limits of the valve before returning the system to service.
