Mueller Refrigeration a-18948 Multi Split Ball Valve Unibody Female X Male Flare 5/8 Inches

Product Description

The Mueller Refrigeration A-18948 is a multi split ball valve designed for refrigerant line service in mini split and multi split HVAC systems. This unibody valve features a female connection on one end and a male flare connection on the other, both sized at 5/8 inches. HVAC technicians use this type of ball valve to isolate refrigerant lines during installation, service, and maintenance of ductless split systems. The unibody construction means the valve body is machined from a single piece of material, which eliminates potential leak points found in multi-piece assemblies. This makes it a reliable choice for high-pressure refrigerant applications where a secure, leak-free seal is critical. The A-18948 is rated to a maximum allowable pressure of 775 psi, or 53 bar, making it suitable for use with common refrigerants including R-410A and R-32 systems that operate at elevated pressures. The valve handles a wide operating temperature range, from -40 degrees Fahrenheit up to 300 degrees Fahrenheit, so it performs reliably in both cold climate installations and high-ambient outdoor environments. Weighing 0.84 pounds, this valve is compact and easy to handle during overhead or tight-space installations. A compatible valve insulation kit is available under part number A 18570U for applications requiring thermal insulation at the valve body. HVAC contractors, refrigeration technicians, and mechanical installers working on multi zone ductless systems will find this valve meets the demands of professional refrigerant line work. Mueller Refrigeration is a trusted manufacturer of valves and refrigeration components used across commercial and residential HVAC markets.
