DNP PLT4 Leak-Free Hydraulic Quick Coupling with Carbon Steel Female Connector
The non-leak flat-face quick-connect coupling is engineered for demanding hydraulic applications, particularly in construction machinery where sudden pressure surges are common. Designed for maximum reliability and ease of use, it allows convenient one-hand operation, ensuring fast and efficient connection and disconnection even in challenging conditions. For systems requiring enhanced safety, the coupling is also available in a version with a static pressure eliminator. Manufactured from high-quality steel with a durable zinc-nickel coating, it guarantees long-lasting resistance to wear and corrosion, even under intensive use. The product complies with ISO 16028 standards (excluding DN5 size) and is fully interchangeable with ISO-F quick couplings from other leading manufacturers, offering flexibility and compatibility across various hydraulic systems. Depending on the operating environment, users can choose between NBR seals, suitable for temperatures from -25°C to +100°C, or viton seals, designed for extreme conditions ranging from -15°C to +200°C. With a working pressure of up to 500 bar, this coupling ensures reliable performance in hydraulic power transmission and industrial applications, making it an ideal solution for professionals seeking efficiency, safety, and durability in their equipment.
