The Stucchi Ball Quick Couplings<\/strong> include two distinct series: IR Series<\/strong>, interchangeable ISO 7241-1 \u201cA\u201d in 1\/2\u201d size, and IV-HP Series<\/strong>, designed for high-pressure applications.<\/p>\n

\n

IR Series \u2013 ISO 7241-1 \u201cA\u201d Interchangeable (only 1\/2\u201d size)<\/h3>\n

The IR Series quick couplings feature a ball locking and shut-off system with single-action sleeve. Coupling and uncoupling are not allowed under pressure. The hardened steel ball valves improve wear resistance. The overall dimensions are compact.<\/p>\n
