Perlast® FFKM seals for oil and gas applications are relied on to overcome the specific challenges found in the upstream, midstream and downstream sectors of the global oil and gas industry.
These specialist components are used in applications including down-hole tools, subsea equipment and infrastructure, pipeline connectors, valves, compressors, pumps and mechanical seals.
Perlast® G92E is a rapid gas decompression (RGD) resistant perfluoroelastomer that can be used in high temperature, high pressure environments, such as ultra-deep water HP/HT applications of 18,000 psi and 177°C (350°F) and above.
Perlast® perfluoroelastomers are used across upstream, midstream and downstream oil and gas applications, to ensure long term reliability and exceptional sealing performance.
Universal chemical resistance
High temperature capability
Rapid Gas Decompression (RGD) resistance
Sour gas resistance
Perlast® is engineered for high temperatures and pressures, but as a perfluoroelastomer material, operators can expect virtually universal chemical resistance.
In critical oilfield applications, this includes steam, amines, polar solvents, aromatic hydrocarbons, oil, fuels and thousands of other chemicals which may corrode less resilient materials.
FFKM O-rings and seals manufactured from Perlast® are resistant to the risk of explosive decompression (ED), otherwise known as rapid gas decompression (RGD).
RGD is a failure mechanism of elastomer seals caused by a rapid reduction in pressure of a gaseous media. Gas that has permeated into the elastomer seal expands violently when the pressure is released, rapidly causing fissuring and seal failure.
PPE’s range of Perlast® materials are tested to a series of international standards, including:
Sour gas can have detrimental effects on elastomer materials. Elastomers which are non-resistant can quickly become hard and brittle, losing their elastic properties and subsequently their ability to seal effectively.
Perlast® materials are certified as resistant to sour gas, to the following international sour gas test standards and conditions:
NORSOK M-710 Annex A – Ageing of elastomeric materials (section 7.2)
ISO 10423 (API 6A) – Petroleum and natural gas industries – Drilling and production equipment – Wellhead and Christmas tree equipment section F.1.13.5.2 (DD/EE and FF/HH)
NACE TM0187 – Elastomeric materials in sour gas environments
ISO 23936-2 Section 7 and Annex A “Petroleum, petrochemical and natural gas industries: Non-metallic materials in contact with media related to oil and gas production – Part 2: Elastomers
These are standard tests. PPE has however gone further, with high concentration testing at 25% H2S rather than the minimum requirement of 2%. These higher concentrations are more representative of real-world conditions, and give a better representation of the efficacy of Perlast® in situ.

Perlast® seals for oil and gas applications
Elastomer sealing components made from Perlast® are engineered for long term reliability in oilfield applications. This minimises the risk of unscheduled downtime and loss of production. Available seal profiles include:
Production packers are a downhole sealing device which is used to isolate the annulus from the production conduit, enabling controlled production, injection or treatment.
