Our 1" male ISO 7241 series A couplers (ISO-A) or Parker 6600 series couplers, are used in a wide range of hydraulic applications including construction equipment, manufacturing machinery, and in-plant systems. The ISO-A style is a durable product using a poppet style valve for the sealing mechanism. These couplers are one of the most popular designs worldwide used in agricultural, mobile equipment, and some industrial applications. These couplers are most commonly known as 6600 series couplers and agricultural couplers. They are also interchangeable with Stucchi "BIR" series.
