Value Collection 9918035085 Miniature Ball Valve 1/8 in

Product Description

The VALUE COLLECTION 9918035085 is a miniature manual ball valve designed for 1/8 inch pipe applications requiring a compact, quarter-turn shutoff solution. The valve body and trim are constructed from brass, with an NBR seal and a polytetrafluoroethylene (PTFE) seat for chemical resistance and low-friction operation. A chrome-plated finish provides additional corrosion protection. The wedge-style handle gives technicians positive tactile feedback for open and closed positions. At 0.16 pounds, this valve is well suited for tight installations where a full-size ball valve will not fit. It is installed by plumbers, HVAC technicians, and pipefitters working on small-bore instrument or control lines.

This valve is intended for small-diameter pipe runs where a reliable manual shutoff is needed in a compact footprint. The FNPT x FNPT end connections allow direct threaded installation into standard female NPT fittings. Typical applications include instrument air lines, chemical feed lines, small refrigerant or gas pilot lines, and other low-flow control circuits found in both light commercial and residential mechanical systems. The 1/8 inch pipe size makes it a common choice for gauge isolation, sample ports, and bypass circuits.

Key Features

• Brass body and trim for durability in small-bore plumbing and instrument applications
• FNPT x FNPT end connections for straightforward threaded installation
• PTFE seat provides low friction and resistance to a wide range of media
• NBR seal material compatible with water, air, and many petroleum-based fluids
• Chrome-plated finish adds corrosion resistance in wet or humid environments
• Wedge handle allows clear visual indication of valve position

Compatibility

Designed as a standard-thread replacement or new-installation miniature ball valve for 1/8 inch FNPT pipe connections in plumbing, HVAC, and instrumentation systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Shut off system pressure and depressurize the line before threading in the valve. Apply thread sealant or PTFE tape to the male NPT fittings being connected to this valve, following applicable plumbing codes such as the IPC or IFGC where gas service is involved. Do not exceed the pressure and temperature ratings of the valve or its connected system components.
