Precision-Crafted Pistons

To ensure that piston designs meet or exceed maximum load requirements, each new design is meticulously evaluated using finite element analysis (FEA) software and years of practical experience.

Pistons are machined from cast iron, aluminum or custom-specified materials. Segmental designs allow incremental repairs, replacing only the worn section of the piston.

Premium Piston Rods

Beginning with the highest-quality mill-certified materials, Cook Compression 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.
