Aeroquip WA5600 series thread-to-connect quick connects are similar to our NS30 series, however, are available for those users who prefer the Aeroquip brand name only. They are an extreme pressure quick connect (10,000 psi) that are commonly found on hydraulic jacks, rams, power packs, and other ultra-high pressure equipment. They are interchangeable with similar couplings in the same size, regardless of the valve style (they are considered an Industrial Hydraulic Interchange so they will not interchange with some Automotive styles). The poppet valving improves sealing, increases burst pressure, and provides less flow restriction (ball or poppet type checks are interchangeable, however ball & poppet type are not designed for use with each other and may affect performance). Compatible with New-Line NS30 series, Parker 3000 series, Enerpac C604, Faster PVV, Dayco QD3 series, Perfecting T series, Safeway S30 series, and many others.
