The PVS screw coupling is a high-performance hydraulic quick coupling engineered for applications exposed to extreme pressures and heavy mechanical loads. Designed for maximum reliability, it is the ideal solution for hydraulic presses, rescue tools, lifting systems, cutters, and other demanding equipment. Its robust construction in carbon steel combined with NBR sealing ensures durability, safety, and long service life even under the toughest conditions. The coupling allows connection and disconnection even when residual pressure remains in the system, significantly increasing efficiency and reducing downtime. With a working pressure of up to 700 bar and impressive burst resistance—up to 2100 bar for the 1/4″ size and 1850 bar for the 3/8″ size when connected—it guarantees secure performance in critical operations. Flow capacity reaches 16.4 l/min for 1/4″ and 21.3 l/min for 3/8″ at Δp = 4 bar, ensuring optimal hydraulic efficiency. The operating temperature range from -25°C to +100°C makes it suitable for diverse environments, from cold outdoor conditions to high-heat industrial settings. End caps are available separately to provide additional protection and extend the service life of the coupling. This product combines strength, precision, and reliability, making it a trusted choice for professionals who demand uncompromising performance in high-pressure hydraulic systems.
