Holyoke Fittings 41fpsw-108 Brass Forged Swivel Flare Nut 5/8 Inches X 1/2 Inches

Product Description

The Holyoke Fittings 41fpsw-108 is a brass forged swivel flare nut designed for reliable connections in plumbing, HVAC, and refrigeration systems. This fitting measures 5/8 inches by 1/2 inches and is built to handle the demands of professional installation work. The forged brass construction gives this flare nut superior strength compared to cast alternatives. Forging aligns the grain structure of the brass, which results in a denser, more durable fitting that holds up under pressure and repeated use. Swivel flare nuts are a preferred choice among HVAC technicians and plumbers because the swivel design allows the nut to rotate independently during installation. This rotation prevents twisting or kinking of tubing as the connection is tightened. That feature saves time on the job and helps protect refrigerant lines and other soft copper or aluminum tubing from damage. The 5/8 inches flare end connects to standard SAE 45-degree flare fittings commonly found in air conditioning, heat pump, and refrigeration line sets. The 1/2 inches end accommodates standard pipe or tubing on the mating side. This size combination is widely used in residential and light commercial HVAC work. Brass is the material of choice for flare fittings because it resists corrosion, seals tightly against metal surfaces, and remains machinable for precision tolerances. The 41fpsw-108 delivers all of these qualities in a compact, job-ready package. This item is sold in a pack of 25 units, making it practical for stocking a service van, supply room, or contractor inventory. The Holyoke Fittings 41fpsw-108 is subject to California Proposition 65 requirements. HVAC technicians, refrigeration mechanics, plumbers, and pipefitters will find this fitting suitable for a wide range of service and installation applications.
