3000 Series Hydraulic Couplings

When your portable rams or high-pressure lines are pushing 10,000 psi, 3000 Series thread-connect couplings keep the connection from backing off. The threaded sleeve lock holds tight, chrome alloy valve balls seal metal-to-metal, polyurethane seals fight extrusion from -65 °F to 180 °F. Choose complete assemblies, female or male couplers or female nipples.
