Parker's dissolvable frac ball sealers are formulated for high strength and controlled dissolution in common wellbore fluids with no post frac intervention required. Several product solutions are available depending on pressure, specific gravity, and dissolution requirements. Product chemistries range from proprietary alloy formulations to reinforced metal matrix composites readily available in production volumes with quick turn delivery. Any size diameter can be made up to 4.500" to tight tolerance and finish.

Our custom packing elements are designed with rugged, high viscosity materials and are optimized for oil field production volumes and complex part configurations.  

We specialize in new-to-world designs to specifically meet the unique challenges of you critical applications.

Parker's chevron packing set with incorporates its proven FlexiSeal® design technology and PTFE-based materials as well as other high performance polymer plastics. Advantages over conventional elastomer-based chevron stacks includes pressure- and wear-resistant PTFE, no special tooling requirements, quick design and short manufacturing times.

Composite metal/polymer chevron sealing systems are used in high pressure, high temperature static and dynamic sealing environments. The stacked, composite design allows for sealing against high pressure hydraulic well-bore fluids and gases.

Our highly-engineered metal seal designs offer customized solutions for demanding applications where extreme temperature, corrosive media, high vacuum and near zero leakage or long life concerns are present. The materials used in our resilient metal seals prevent gaseous permeation while providing exceptional performance in critical vacuum applications.

As a specialist in engineered materials, engineering design and process technology Parker Prädifa offers an extensive portfolio of large-size seals and moldings made of polymers such as NBR, EPDM, FKM, PTFE and PEEK, as well as metal. Machined up to 4.5 m or continuously vulcanized in any desired size. Spring-energized metal C-rings with a diameter of up to 7.6 m.

The ability to use materials which have been tested and approved via an industry standard test gives the end user a confidence that is unobtainable for other products.

Parker offers compounds from the HNBR, FKM, AFLAS and FFKM families which have been tested for Sour Service and Rapid Gas Decompression (RGD) standards such as API 6A, NORSOK M-710, ISO23936-2 and TOTAL GS EP PVV 142.

Gask-O-Seals® are uniquely designed elastomeric elements which are molded directly into grooves to produce an integrated sealing solution.

As directional drilling becomes more complex, precision measurement while drilling (MWD) is used to assure smooth operation of the borehole or well. Custom Gask-O-Seal solutions for MWD applications assure high sealing reliability as well as part reusability with easy installation. 

Parker Prädifa´s high-performance Perfluoro O-rings are suitable for extreme chemical and thermal requirements and approved according to the industry´s standards (RGD, sour service). They are manufactured according to AS 568B and complementary international standards. Precision O-rings in XXL sizes are available, manufactured by continuous molding technology.
