Eaton A6775 Straight Needle Valve 3/8 in Compression Brass

Product Description

The EATON A6775 is a straight-pattern needle valve designed for precise flow control in low-to-medium pressure systems. Built with a brass body and compression-to-compression end connections in 3/8 inch pipe size, this valve provides repeatable shutoff and throttling capability. The overall assembly length is 1.5 inches, and the valve is rated for a maximum working pressure of 150 psi. It is commonly installed by licensed plumbers, HVAC technicians, and refrigeration service professionals where fine flow regulation is required on liquid or gas lines.

This valve is suited for residential and light commercial applications where a compact straight-pattern needle valve is needed in a compression-fitting configuration. Typical installations include instrument lines, sample lines, fuel lines, and HVAC equipment connections where controlled flow or positive shutoff at low to moderate pressures is the primary requirement. The brass body offers good compatibility with water, air, and many common refrigerants and fuels within its rated pressure range.

Key Features

• Straight-pattern body for in-line installation with minimal pressure drop
• Compression x compression end connections in 3/8 inch pipe size
• Brass body construction for corrosion resistance in plumbing and HVAC service
• Rated to 150 psi maximum working pressure
• Compact 1.5 inch overall length fits tight equipment spaces
• Needle-style trim provides precise throttling and positive shutoff

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for 3/8 inch compression-fitting applications in residential and light commercial plumbing, HVAC, and instrumentation systems rated to 150 psi or below.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off supply pressure and depressurize the line completely before removing or installing any valve. Compression fittings must be properly seated and tightened to the fitting manufacturer specifications using appropriate tubing wrenches — do not overtighten. Verify that the media, temperature, and pressure conditions of the application fall within the valve rating before returning the system to service.
