    Rod Rings


    As the inventor of floating mechanical packing over a century ago, Cook is unmatched in application experience. Cook has supplied rod rings for tens of thousands of successful applications worldwide.

    Continued development, backed by experienced applications support, results in custom seal ring, pressure breaker and wiper solutions that consistently outperform traditional approaches. A complete selection of materials, from bronze to high-performance non-metallics, dramatically improves durability in the most demanding applications.

    Cook Compression solid packing rings, for example, minimize reciprocating compressor gas leakage at its primary source – in the packing case along the piston rod. Unlike traditional radial and tangent cut rings, uncut rings have no gaps, eliminating leak paths. In addition, the compressive properties of the ring materials are engineered to provide sealing with less frictional load than traditional rod rings. As a result, Solid Ring Technology seals more effectively, especially at higher pressures.

    Innovative RTV oil wiper packing effectively removes lubricating oil film from the compressor rod while creating a continuous gas seal between the crankcase and distance piece. This dual function virtually eliminates oil leakage as well as the harmful effects of fugitive emissions.
