Eaton 330 Needle Valve Flare Angled 3/8 X 1/4 in Brass

Product Description

The EATON 330 is a flare-angled needle valve designed for precise flow control in refrigerant and fluid handling systems. Built with a brass body, it connects a 3/8-inch flare inlet to a 1/4-inch male NPTF (MNPTF) outlet in an angled configuration. The overall height (OAH) is 1.84 inches, making it compact enough for tight service locations. It is rated to a maximum working pressure of 150 psi. Licensed HVAC technicians and refrigeration mechanics are the primary installers. The angled flare style allows the technician to direct tubing routing without adding separate fittings, reducing potential leak points in the line.

This needle valve is suited for residential and light commercial HVAC and refrigeration applications where a flare-to-MNPTF transition and directional flow control are required at a single fitting. The angled body style is commonly used in equipment service ports, manifold connections, and refrigerant line access points where straight inline valves would create routing conflicts. Its compact 1.84-inch profile fits well in confined equipment cabinets and service panel areas.

Key Features

• Angled flare configuration routes tubing without additional elbow fittings
• Brass body provides corrosion resistance in refrigerant and fluid service environments
• 3/8-inch flare inlet to 1/4-inch MNPTF outlet transition in a single fitting
• 150 psi maximum working pressure rating
• Compact 1.84-inch overall height fits confined installation spaces

Compatibility

Designed as an OEM-style replacement or service fitting for HVAC, refrigeration, and fluid control systems requiring a 3/8-inch flare by 1/4-inch MNPTF angled needle valve connection.

Installation Notes

Installation is typically performed by licensed HVAC technicians or refrigeration mechanics. Recover and isolate any refrigerant charge and depressurize the line before removing or installing this valve. Flare connections must be made to properly flared tubing using calibrated flaring tools to ensure a leak-free seat. Verify system pressure does not exceed the 150 psi rating before returning the system to service.
