Mueller Refrigeration av1h-fa21a Packed Line Valve 1/4 Inches X 1/4 Inches Angle Non-backseating Nptfe Inlet to Flare Double O-ring Seal

Product Description

The Mueller Refrigeration av1h-fa21a is a packed line valve designed for use in refrigeration and HVAC systems. It features a 1/4 inch NPTF inlet connecting to a 1/4 inch flare outlet in an angle body configuration. The non-backseating design keeps the valve stem fully contained during operation, which is a preferred setup in many commercial and residential refrigeration applications. A double O-ring seal provides two layers of protection against refrigerant leaks, helping technicians maintain system integrity over the long term. The valve body is made from brass, a material known for its resistance to corrosion and its compatibility with common refrigerants and refrigeration oils. Brass construction also holds up well under the temperature swings typical in refrigeration lines. This valve is rated for a maximum working pressure of 900 psi, making it suitable for high-pressure refrigerant systems including those using R-410A and similar modern refrigerants. The FL x NPTF connection type makes it straightforward to integrate into existing refrigerant lines without special adapters. HVAC technicians and refrigeration service pros use packed line valves like this one to isolate sections of a refrigerant circuit for service, charging, or evacuation. The angle body orientation helps route piping cleanly in tight equipment spaces such as condensing units, air handlers, and commercial refrigeration cabinets. This valve measures 3 inches in length, 0.9 inches in width, and 1.28 inches in height, with a weight of 0.327 pounds. It ships as a single unit and is manufactured with California Proposition 65 compliance in mind. A reliable choice for line valve replacement or new installation in refrigerant service applications.
