1/2 ISO 7241 Poppet Pioneer Hydraulic Quick Coupler 4 sets

The ISO 7241-1 A Series Hydraulic Quick Disconnect Coupler Set is a high-performance, general-purpose solution for medium and high-pressure hydraulic systems. Built to the ISO 7241-1 Series A international standard, these couplings deliver reliable, leak-free connections and are fully interchangeable with leading brands such as Parker, Aeroquip, Stucchi A series, and equivalent models.Made from high-grade carbon steel with zinc plating, the couplers offer excellent durability, long service life, and high burst pressure for tough working conditions. The precision poppet valve design ensures tight sealing under pressure, reduces fluid loss, and maintains system cleanliness during quick connect and disconnect operations. The ball-latch locking sleeve enables fast, one-hand connection and disconnection without tools, improving efficiency and safety during maintenance or equipment changes.This set includes 4 male couplers, 4 female couplers, and optional dust caps to protect threads and seals when not in use. Ideal for tractors, agricultural machinery, loaders, excavators, forklifts, machine tools, and other mobile or industrial hydraulic equipment.Key SpecificationsStandard: ISO 7241-1 Series AMaterial: Carbon steel, zinc-platedValve type: Poppet valveConnection: Ball-latch quick connectThread: 1/2 NPTSize: 1/2"Nominal Flow Rate: 12 GPMMax Flow Rate: 24 GPMWorking Pressure: 3000 PSI / 210 BarBurst Pressure: 9000 PSI / 630 BarApplication: Agriculture, construction, industrial hydraulicsProfessional build quality, consistent performance, and wide compatibility make these quick disconnect couplings an excellent choice for your hydraulic system needs.
