New O-Ring Compound Provides Excellent Resistance to EOG Industry Hazards

December 12, 2006 - Parker Seal Group's O-Ring Division has developed the new VP104-85 compound for O-rings and other rubber seals for the energy, oil and gas markets.

The new material, which uses the successfully-tested Solvay Solexis BR 9151 polymer, is resistant to sour gas, acids, bases, hydrocarbons, hot water, steam, amines, and methanol. It also is explosive decompression resistant.

Traditional fluorocarbon compounds are limited in their compatibility with sour gas and many of these other chemistries do not provide good resistance to bases, hot water, amines, steam, or methanol. VP104-85's features combine to make the material an ideal choice for O-rings and seals used for offshore drilling, exploration and production applications, including drilling mud, some completion fluids, brine, sour gas and crude oil.

Parker O-Ring Division products are at the leading edge of elastomer technology. Parker O-Ring Division offers a broad spectrum of materials for oilfield sealing applications ranging from the chemically resistant, high temperature Parofluor(TM) and Parofluor ULTRA(TM), to a variety of premium elastomeric sealing materials.

Throughout every phase of the process from exploration to the pump, and for whatever extremes an application demands, Parker O-Ring Division has the products to meet EOG industry sealing requirements. Whether it is an "off-the-shelf" industrial standard or a material in a custom size developed to customer specifications, our commitment to service is designed to minimize downtime. In addition to O-Rings Parker O-Ring Division offers ParBak(TM) anti-extrusion rings, installation lubricants and O-Ring assembly and removal tools. Our manufacturing plants are ISO 9001, ISO/TS 16949:2002 and QS 9000 registered.
