Premium Piston Rods
Beginning with the highest-quality mill-certified materials, Cook engineers and manufactures compressor rods that perform reliably and deliver lasting value. Subject to application requirements, rods are induction hardened or tungsten carbide coated to resist wear and extend run times for both the rod and rod packing. Other coatings and surface treatments are also available.
Cook rods are manufactured with rolled threads, which dramatically increases strength and eliminates stress risers.
