Eaton 6825 Straight Needle Valve 1/4 Inch Brass 150 Psi

Product Description

The EATON 6825 is a straight-pattern needle valve designed for precise flow control in plumbing and fluid-handling systems. Built with a brass body, this valve connects via female NPT inlet to male NPT outlet (FNPTF x MNPTF) on 1/4-inch pipe. It carries a maximum working pressure rating of 150 psi, making it suitable for low-pressure liquid and gas service lines. The overall assembled length is 1.87 inches. Plumbers, pipefitters, and HVAC technicians install this valve where fine-flow regulation is needed in tight-quarter installations.

The EATON 6825 fits residential and light commercial applications that require throttling or shut-off control on small-diameter pipe runs. Typical use cases include instrument sensing lines, gauge isolation, fuel lines, and compressed air or refrigerant service ports where a 1/4-inch connection is specified. The straight-body configuration makes it a straightforward inline replacement or new-install valve in any system calling for 1/4-inch NPT threading.

Key Features

• Straight-pattern design for simple inline installation on 1/4-inch pipe
• Brass body construction for corrosion resistance in fluid and gas service
• FNPTF x MNPTF end connections for standard NPT threaded pipe systems
• 150 psi maximum working pressure rating
• Compact overall length of 1.87 inches suits confined spaces
• Lightweight at 0.20 pounds for easy single-handed installation

Compatibility

Designed as an OEM-style replacement or new-install straight needle valve for systems using 1/4-inch NPT threaded connections rated to 150 psi or below.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC or local plumbing code requirements. Shut off and fully depressurize the system before removing or installing any valve. Apply thread sealant or PTFE tape to the male NPT threads per standard practice before making up connections. Do not exceed the 150 psi maximum working pressure rating for the service application.
