RC-TRIO is the next generation of the legendary Enerpac RC-Series single acting hydraulic cylinders. These hydraulic jacks include many advanced features to ensure superior durability, versatility, and productivity. A pre-tensioned spring provides fast plunger retraction and enhanced productivity. The robust bearing system features composite wear bands and a hardened stop ring to resist side-load which minimizes damage and repairs. The plunger wiper, high-grade polyethylene seals and tough external finishes also help towards an extended service life. With so many hydraulic cylinder models to choose from, we’re confident you’ll find the perfect match for your applications, and if you already own prior RC-Series cylinders, the good news is the new cylinders share the same familiar dimensions and threads for full compatibility.
