As a manufacturer of pneumatic cylinders, we specialize in the industrial tie-rod design - both the standard NFPA interchangeable tie-rod design and the custom design. Our air cylinders are truly permanently self-lubricated with the proprietary Miracalube® System. The Miracalube® lubricant is made of FDA approved materials and does not mist into the atmosphere. Our cylinder construction is the standard brass and steel design or the all-stainless steel cylinder.
