The Stucchi High Pressure Quick Couplings<\/strong> include the A-HP<\/strong> and IV-HP<\/strong> series, developed for high-pressure applications up to 700 bar in the most demanding hydraulic sectors. Both series offer compact, modular and robust configurations with clearly defined technical specifications.<\/p>\n

\n

A-HP Series<\/h3>\n

The A-HP Series<\/strong> features a flat face valve that facilitates cleaning, reduces contamination in the hydraulic circuit and minimizes both fluid leakage during disconnection and air inclusion during connection. The internal design is optimized to reduce pressure drop and improve circuit efficiency.<\/p>\n
