• Cone and V-ring Packing

    The most important feature of stuffing box packing is long-lasting performance. NOV continually tests new and better materials to meet the demands for ever-changing well conditions. Extensive field tests make certain new packing stand up to stringent durability and performance standards. Cone packing is available in sizes for all polished rods 1" through 1 ¾" in sets of four (3 top cone and 1 bottom cone) and five (4 top cone and 1 bottom cone).

     

    Description

    Packing TypeDescription
    Hercules GoldFor sweet crudes with high oil-to-water ratios, low sand content and where salt
    or corrosion buildups on polished rod have caused premature wear of other packings
    Soft Cone PackingFor sweet crudes with high oil-to-water ratios and low sand content
    Hard Cone PackingFor sweet crudes with low oil-to-water ratios
    Slick Pack™ (Compound S™)For reducing polished rod noise "squeaking" in noise-sensitive locations on
    crudes with high oil-to-water ratios and low sand content
    Special LubricatedFor sweet crudes with high oil-to-water ratios and low sand content
    Heavy-dutyFor prolonged service on sweet crudes and wells without constant flow
    PTFE FilledFor sweet crudes and wells with long stroke and fast pumping cycles
    Compound CFor steam injection wells producing sweet crudes
    Coupound GFor H2S and CO2 wells
    Slick Pack with
    Teflon Flakes (Compound ST)
    For reducing polished rod noise ("squeaking") in noise-sensitive locations on
    sweet crudes that pump off or have long stroke and fast pumping cycles
    Compound DFor steam injection wells where polished rod scoring is a concern
    Compound HFor steam injection wells

Each downhole condition is different and must be addressed on a case-by-case basis to determine the best material solution for each particular well.
