Eaton A6765 Needle Valve 1/4 Inch Compression Brass 150 Psi

Product Description

The EATON A6765 is a straight needle valve designed for precise flow control in compressed-fluid and instrumentation lines. Built with a brass body, this valve uses compression-to-compression end connections on a 1/4-inch pipe size, making it a reliable choice for low-to-medium pressure service rated to 150 psi maximum working pressure. The overall assembled length is 1.13 inches. Plumbers, HVAC technicians, and instrumentation installers use this type of valve to throttle or shut off flow with fine-tuned accuracy in tight plumbing assemblies. The brass construction provides good corrosion resistance in water and many light-duty fluid applications.

This needle valve is suited for residential and light commercial plumbing, HVAC, and instrumentation applications where controlled flow restriction is required. The compression-by-compression end configuration allows tool-accessible installation without soldering, making it practical for retrofits and service work in confined spaces. Typical applications include instrument tubing tie-ins, sample lines, and low-flow control points in water or compatible fluid systems.

Key Features

• Straight-body configuration for in-line installation
• Compression x compression end connections — no soldering required
• Brass body construction for corrosion resistance in water and compatible fluids
• Rated to 150 psi maximum working pressure
• 1/4-inch pipe size suits standard instrumentation and light plumbing tubing
• Compact 1.13-inch overall length for tight-space installations

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for 1/4-inch compression fitting assemblies in plumbing, HVAC, and instrumentation systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified technician. Shut off system pressure and relieve line pressure completely before removing or installing any valve. Compression fittings require proper tube preparation and seating — do not overtighten, as this can deform the ferrule and cause leaks. Verify that the line fluid and operating pressure are compatible with brass body construction before installation.
