Oil & Gas Sealing Solutions

High-Performance Seals for Extreme Oil & Gas Environments

At Ashton Seals, we provide high-performance sealing solutions for the oil and gas industry, specifically engineered to operate in high-pressure, high-temperature, and chemically aggressive environments. Supporting applications from upstream exploration through to downstream processing, our seals ensure reliable performance, operational safety, and long-term durability in critical systems where failure is not an option.

With extensive industry experience, we supply solutions for a wide range of conditions from cryogenic systems to demanding NORSOK M-710 down hole environments demonstrating the versatility and resilience of our products. We offer both standard catalogue seals from our extensive stock range and fully bespoke sealing solutions, designed to meet the challenges of extreme and specialized applications.

Sealing Solutions Across the Oil & Gas Sector

We provide sealing solutions for all stages of oil and gas operations:

Upstream (Exploration & Production)

• Drilling and wellhead equipment
• Sub sea and down hole systems
• High-pressure valves and connectors

Midstream (Transport & Storage)

• Pipelines and pumping stations
• Compression systems
• Storage facilities

Downstream (Refining & Processing)

• Refineries and petrochemical plants
• Processing equipment and vessels
• Heat exchanges and pressure systems

These applications require high-integrity sealing solutions capable of maintaining performance under extreme pressure, temperature and chemical exposure.

Extreme Conditions & Performance Requirements

Oil & gas environments are among the most demanding in any industry:

• High pressure (often exceeding hundreds of bar)
• Extreme temperatures (from cryogenic to +200°C+)
• Exposure to aggressive chemicals, hydrocarbons, and gases
• Risk of rapid gas decompression (RGD) in sealing materials

Effective sealing solutions help:

• Prevent leaks and environmental hazards
• Maintain system pressure and integrity
• Protect equipment from failure
• Ensure operational safety and compliance

Industry Standards & Certifications

Sealing solutions in oil & gas must meet strict international standards:

• Key Oil & Gas Certifications
• NORSOK M-710 – Qualification of non-metallic sealing materials for oil & gas applications
• API (American Petroleum Institute) standards – e.g. API 6A, API 6D for pressure systems
• ISO 23936 / ISO 3601 – Material compatibility and O-ring standards
• RGD resistant
• High Temp steam resistant
• High pressure resistant
• Sour Gas (H2S) & Hydrocarbon compatible ​
•  

Additional Requirements:

• ISO 9001:2015 – Quality management systems
• ISO 4406 – Hydraulic fluid contamination control (critical for seal life)
• ATEX compliance (where applicable) for explosive environments

These standards ensure sealing components are safe, reliable, and suitable for critical oil & gas operations.​

Products for Oil & Gas Applications

We supply a comprehensive range of sealing products for oil and gas environments including:

• O-rings and elastomer seals (including RGD-resistant materials)
• Metallic and semi-metallic gaskets
• Hydraulic and high-pressure seals
• PTFE and engineered sealing solutions
• Custom gaskets and sealing systems

Materials such as PTFE are widely used due to their chemical resistance, low friction, and wide temperature range​.

Materials & Performance

Oil & gas sealing solutions must be carefully selected for compatibility and durability.

We offer materials that provide:

• Resistance to hydrocarbons, chemicals, and sour gas
• Stability under high pressure and temperature extremes
• Protection against rapid gas decompression (RGD)
• Long-term reliability in critical sealing applications

Common materials include:

• FKM (Viton®) – high temperature and chemical resistance
• FFKM – extreme chemical and thermal environments
• HNBR – enhanced mechanical and oil resistance
• PTFE – low friction and chemical stability  

Typical Applications

Our sealing solutions are used across a wide range of oil and gas systems:

• Down hole tools and wellhead equipment
• Sub sea systems and offshore platforms
• Pipelines and pressure vessels
• Pumps, valves, and compressors
• Refining and processing equipment

These applications require high-integrity sealing to ensure safety, environmental protection and operational efficiency.

• Filling arms
• Horizontal drilling and fracturing
• Sliding sleeve systems
• Natural gas extraction

Frequently Asked Questions

1. What seals are used in oil and gas applications?
Common sealing solutions include O-rings, metallic gaskets, hydraulic seals and PTFE components designed for high-pressure and chemically aggressive environments.
2. What is NORSOK M-710?
NORSOK M-710 is a standard used to qualify non-metallic sealing materials for oil and gas applications, ensuring resistance to rapid gas decompression and harsh conditions.
3. Why is RGD resistance important in seals?
Rapid gas decompression can damage seals in high-pressure gas environments. RGD-resistant materials prevent cracking and failure.
4. What materials are used for oil and gas seals?
Materials such as FKM, FFKM, HNBR, and PTFE are commonly used due to their resistance to chemicals, temperature and pressure extremes.
5.Can oil and gas seals be customized?
Yes, sealing solutions can be engineered to meet specific application requirements, including extreme environments and specialized equipment.
