• Enerpac hollow plunger cylinders allow for both pull and push forces
• Double-acting cylinder version for fast retraction
• Relief valves prevent damage in case of over-pressurisation
• Baked enamel finish for increased corrosion resistance
• Collar threads enable easy fixturing (except RRH-1001 and RRH-1508)
• Nickel-plated, floating center tube increases product life
• CR-400 coupler and dust cap included on all hollow plunger models
• Plunger wiper reduces contamination, extending cylinder life.
