The Type A3 coupling is a robust solution for securely connecting pneumatic components, including hoses, in demanding industrial environments. Crafted from durable nickel-plated brass, it ensures long-lasting resistance to wear, corrosion, and mechanical stress, even under intensive use. To guarantee a perfectly sealed connection, additional sealing elements are required—Teflon tape or sealant for tapered threads, and aluminum or copper washers for cylindrical threads. With an impressive working pressure capacity of up to 60 bar, this coupling delivers reliable performance in high-pressure applications, making it an excellent choice for professionals seeking efficiency, safety, and durability in their pneumatic systems.
