Hydraulic Cylinders Inc.’s Series 3 NFPA Tie-Rod Cylinders are made to order for 1.5″–6″ bore pneumatic applications. They provide smooth push/pull motion for industrial equipment. Built in the USA to NFPA-interchangeable size standards, they help ensure consistent fit across common mounts and simplify replacement planning. Series 3 cylinders use an aluminum body, a flush-mount standard design, and standard cushions to reduce end-of-stroke impact. Options include oversize rods, stainless components and tubing, non-rotating styles, rod locks, and air/oil tanks.
