Legris 7915 08 14 Miniature Ball Valve 5/16 in Mnpt

Product Description

The LEGRIS 7915 08 14 is a miniature manual ball valve designed for 5/16-inch pipe applications with an MNPT x Push-To-Connect end connection. The valve features a standard port configuration and a composite body with nickel-plated brass trim, offering a balance of chemical resistance and durability in compact fluid control systems. Buna-N seals and seat material provide reliable sealing against common hydraulic fluids and water-based media. A short red handle gives quick visual indication of valve position and allows manual actuation in tight spaces. Weighing 0.15 pounds, this valve is well suited for instrument tubing, pneumatic lines, and small-bore process connections where space and weight are constraints.

This valve is typically installed in residential and light commercial applications involving compressed air, water, or compatible fluid systems where a compact shutoff point is needed at a push-to-connect fitting interface. The MNPT male thread side connects directly to female-threaded ports or manifolds, while the push-to-connect end accepts tubing for tool-free insertion. Plumbers, HVAC technicians, and instrumentation technicians working with small-bore tubing runs will find this valve useful at branch isolation or inline shutoff points. The 1/4-inch thread size is standard across a wide range of fittings and equipment ports.

Key Features

• Composite body construction reduces weight and resists corrosion in compatible media
• Nickel-plated brass trim provides durability at the connection interfaces
• Buna-N seat and seal material rated for common hydraulic fluids and water-based media
• MNPT x Push-To-Connect end configuration allows fast, tool-free tubing installation on one end
• Short red handle enables actuation in confined spaces and provides immediate open/closed visual reference
• Standard port design delivers consistent flow through the valve body

Compatibility

Designed as an OEM-style miniature ball valve for 5/16-inch pipe systems using MNPT x Push-To-Connect fittings with a 1/4-inch thread size in pneumatic, instrumentation, or small-bore fluid control applications.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or instrumentation technician familiar with small-bore fluid or pneumatic systems. Depressurize and isolate the system fully before removing or installing any valve. Apply thread sealant appropriate for the media on the MNPT male threads and torque to fitting manufacturer recommendations only. The push-to-connect end requires clean, burr-free tubing cut to a square end for proper seating and leak-free engagement.
