C300 EXTREME PRESSURE COUPLINGS

C300 thread-to-connect couplings are designed for high pressure ap plications found on torque wrenches, hydraulic jacks, and other con struction and demolition equipment. Couplings are made from zinc plated carbon steel and come standard with polyurethane and buna-N (Nitrile) seals. They feature ball-style valves, allow for bidirectional flow, and can be connected with low resifdual pressure in the hydrau lic circuit. The thread-to-connect design eliminates brinelling. Temperature Range : -30°C (-22°F) to 105°C (221°F). Interchange : Parker 3000, Enerpac C604, Faster PVV, Holmbury PSB.

C300KM Series high pressure poppet valve couplings are primarily used on bolt tensioners, hydraulic jacks, hydraulic hammers, and other high pressure applications. The carbon steel construction with black zinc-nickel plating offers superior corrosion resistance. These couplings are rated to 21750 psi, come standard with buna-N (Ni trile) seals, and allow for bidirectional flow. Temperature Range : -40°C (-40°F) to 105°C (221°F). Interchange : Holmbury KM.
