90-Degree Male DIN adapters are essential fittings in hydraulic systems, designed to provide secure, leak-free connections. DIN fittings feature a 24° tapered throat angle inside the male threads, which allows for a reliable tube connection when a tube nut is tightened over the metric threads. This tightening action forces a ferrule or cutting ring to grip the tube, creating a secure seal. The nut and cutting ring work together to hold the assembly in place and prevent leaks. DIN fittings, including Kobelco fittings, are available in three pressure classes—LL (Extra Light Duty), L (Light Duty), and S (Heavy Duty)—to accommodate varying system requirements. These adapters are ideal for high-pressure fluid power systems, offering durability and flexibility in applications that demand reliable performance. They are commonly used in industrial environments, where secure, efficient fluid transfer is critical.
