Gazguard Elastomers

High performance elastomers engineered for demanding applications

Freudenberg Oil & Gas Technologies is a leader in elastomer materials technology. Our extensive portfolio of elastomeric capabilities includes our proprietary Gazguard® material, designed to minimize the risk of damage from explosive decompression, also known as Rapid Gas Decompression (RGD).

Gazguard® compounds are designed to have exceptional physical and chemical durability, making them ideal for extreme operating environments. All are certified according to the stringent requirements of Norsok M-710 RGD, Norsok M-710 sour gas and ISO 10423 (API 6A) chemical aging immersion and fixture testing, and ISO 10423 F.1.11 pressure and thermal cycling testing.

Specific examples of certified performance of our Gazguard® compounds include the 728 compund, which has been certified to material class FF/HH per ISO 10423:2009 and ANSI/API Specification 6A Twentieth Edition, within 10% H2S / 10% CH4 / 80% CO2 and Jet Fuel A. Also, our Gazguard® 775 material has been designed for use within Blow Out Preventer (BOP) seals and is certified under API 16 A 4th edition testing for temperatures up to 350°F and has passed the requirements of Norsok M-710 RGD and Norsok M-710 sour gas testing up to 10% H2S. Certifications are available for download below. 

Our Gazguard® materials have been used extensively in packer elements, seal stacks, spring seals (S, S), T Seals, liner hanger packers, pump down plugs, liner wiper plugs and within specialty sealing solutions for oil and gas drilling, completing and production applications.
