Oil and Gas Sealing

High-Performance Sealing Solutions for the Oil & Gas Industry

In the oil and gas sector, sealing components operate under some of the toughest conditions on earth. Extreme pressures, corrosive chemicals, broad temperature swings and the constant risk of downtime. Selecting the right material is critical for safety, efficiency and long-term reliability.

Advanced polymers such as PTFE, PCTFE, PPS, PEEK and PI have become essential materials for high-performance sealing solutions in upstream, midstream and downstream operations. Their unique combinations of chemical resistance, thermal stability and mechanical strength allow them to outperform traditional elastomers and metals in demanding environments.

Below is an overview of the key materials we supply, their benefits and where they are typically used across the industry.

Why Advanced Polymers Are Transforming Oil & Gas Sealing

PTFE Sealing Solutions

Why PTFE?

PTFE (Polytetrafluoroethylene) is one of the most widely used sealing materials in oil and gas, thanks to:

  • Exceptional chemical resistance
  • Ultra-low friction
  • Wide operating temperature range
  • Non-stick, non-ageing and UV-resistant properties

Typical Applications

  • Valve stem seals
  • Pump diaphragms
  • Gaskets and static seals
  • Compressor components
  • Cryogenic sealing elements

PTFE is ideal when equipment is exposed to aggressive chemicals, high temperatures or demanding motion profiles.

 

PEEK Sealing Solutions

Why PEEK?

PEEK (Polyether Ether Ketone) is one of the strongest polymers used in the oil and gas industry, offering:

  • Outstanding mechanical strength
  • High-pressure and high-temperature capability
  • Resistance to steam, sour gas and aggressive chemicals
  • Excellent wear and creep properties

Typical Applications

  • HPHT (High-Pressure High-Temperature) seals
  • Downhole tools
  • Backup rings
  • Anti-extrusion components
  • Compressor and subsea sealing elements

PEEK is the go-to material for extreme pressure/temperature sealing systems where failure is not an option.

 

Polyimide (PI) Sealing Solutions

Why PI?

PI (Polyimide) delivers exceptional thermal stability and mechanical strength, especially in dry-running or high-friction environments. Key advantages:

  • Withstands temperatures exceeding 300°C
  • Excellent wear and fatigue resistance
  • Low creep and dimensional stability
  • Outstanding performance in high-speed equipment

Typical Applications

  • Compressor and turbine seals
  • High-speed rotating equipment
  • Backup rings for HPHT applications
  • Dry-running sealing interfaces

Polyimide’s combination of heat resistance and wear performance makes it ideal for critical rotating equipment.

 

PCTFE Sealing Solutions

Why PCTFE?

PCTFE (Polychlorotrifluoroethylene) excels in applications where gas impermeability and dimensional stability are essential. It offers:

  • Very low gas permeability
  • Excellent resistance to cold flow
  • Superior performance in cryogenic environments
  • High resistance to chemicals and moisture

Typical Applications

  • LNG valves and pump seals
  • High-pressure gas systems
  • Cryogenic service seals
  • Static sealing components requiring stability at low temperatures

PCTFE is the material of choice for liquid natural gas and high-purity gas handling systems.

 

PPS Sealing Solutions

Why PPS?

PPS (Polyphenylene Sulphide) is a high-temperature, high-strength polymer used when mechanical durability is paramount. Its benefits include:

  • High-dimensional stability
  • Resistance to hydrocarbons and corrosive fluids
  • Excellent wear resistance
  • Thermal stability up to ~200°C

Typical Applications

  • Bearing cages and backup rings
  • Pump and compressor components
  • Seals exposed to abrasive and chemically aggressive media

PPS performs reliably in hot, wet and chemically harsh operating environments.

 

Why Advanced Polymers Are Transforming Oil & Gas Sealing

Across drilling operations, refining processes, subsea installations and LNG systems, polymer-based sealing solutions offer major advantages, including:

  • Increased equipment life through reduced wear
  • Lower maintenance costs due to enhanced chemical and temperature resistance
  • Improved safety by preventing leaks and handling aggressive media
  • Higher reliability in HPHT and corrosive service environments
  • Lightweight, corrosion-free and predictable performance

As operating conditions become more extreme, the selection of advanced polymer materials will continue to play a crucial role in system integrity and operational efficiency.
