C300 EXTREME PRESSURE COUPLINGS

C300 thread-to-connect couplings are designed for high pressure C300KM Series high pressure poppet valve couplings are primarily
applications found on torque wrenches, hydraulic jacks, and other used on bolt tensioners, hydraulic jacks, hydraulic hammers, and
construction and demolition equipment. Couplings are made from other high pressure applications. The carbon steel construction
zinc-plated carbon steel and come standard with polyurethane with black zinc-nickel plating offers superior corrosion resistance.
