Eaton 320 Needle Valve Flare Angled 1/4 X 1/8 in Brass

Product Description

The EATON 320 is a flare-angled needle valve designed for precise flow control in refrigeration and HVAC service applications. Built with a brass body, it connects a 1/4-inch flare inlet to a 1/8-inch male NPT fitting (MNPTF), making it well suited for low-volume, high-precision shutoff tasks. The valve carries a maximum working pressure rating of 150 psi and measures 1.54 inches overall height. HVAC and refrigeration technicians install this valve where an angled flare-to-NPT transition is required in compact service assemblies.

This valve is appropriate for residential and light commercial refrigeration systems, HVAC service manifolds, and refrigerant line assemblies where a reliable angled needle valve with a flare-to-male-NPT connection is specified. The angled body style accommodates installations where straight-body valves would not clear adjacent components or tubing runs. It is typically installed by licensed HVAC-R technicians during system service, retrofit, or new construction work.

Key Features

• Angled flare body style allows installation in tight or offset plumbing configurations
• Brass body construction provides corrosion resistance in refrigerant and refrigeration-oil environments
• 1/4-inch flare inlet to 1/8-inch MNPTF outlet for direct flare-to-NPT transition
• 150 psi maximum working pressure suits common HVAC-R service pressures
• Compact 1.54-inch overall height fits space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or service valve for HVAC-R systems requiring a flare-angled needle valve with a 1/4-inch flare by 1/8-inch MNPTF connection and a maximum working pressure of 150 psi.

Installation Notes

Installation should be performed by a licensed HVAC-R technician. Recover and evacuate refrigerant from the system before removing or installing any valve in the refrigerant circuit, in accordance with EPA Section 608 regulations. Use proper flare tools to ensure a leak-free flare seat connection, and apply thread sealant rated for refrigerant service on the MNPTF threads only. Do not exceed the 150 psi rated working pressure during pressure testing or system operation.
