Ultra Pressure Components Series 5404 Male JIC x Male NPT High Pressure Adapters are engineered to connect JIC fittings with NPT threads, offering high-pressure performance up to 15,000 psi (689 bar). These adapters feature a 37-degree cone seal for reliable, leak-proof connections and are made from durable cold-worked 316 stainless steel, ensuring resistance to corrosion and wear. While JIC fittings are standard for their robust pressure capabilities, NPT fittings can handle pressures up to 15,000 psi (1034 bar), with variations depending on thread size. Custom material options are available for both types, making them versatile for demanding applications.
