PTFE Gaskets for Oil and Petrochemical Refineries – Proven Fugitive Emission Sealing

22 September 2025

PTFE Ring Gaskets
Secure dependable sealing with Gasketech Melbourne PTFE gaskets for oil and petrochemical refineries, ensuring long-term control of fugitive emissions.

Reliable sealing technology is vital for maintaining operational integrity in oil and petrochemical refineries. PTFE gaskets are crucial for controlling fugitive emissions, enabling plants to meet stringent environmental regulations while preventing costly downtime. At Gasketech, we deliver precision-engineered gaskets designed to protect assets, safeguard personnel, and ensure regulatory compliance.

Fugitive Emissions and Their Impact on Refineries

Fugitive emissions are unintended gas or vapour releases from pressurised equipment, often caused by leaks in valves, flanges, or pipeline connections. These emissions contribute to air pollution, increase fire and explosion risks, and can lead to heavy fines for non-compliance.

Worn gaskets, degraded seals, and poor joint maintenance are common causes of fugitive emissions. With tightening global regulations, refineries must adopt advanced sealing solutions like PTFE gaskets to ensure safety and maintain uninterrupted production.

PTFE as the Preferred Gasket Material

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer known for its unique molecular structure, which creates a low-friction, non-reactive surface. This composition provides exceptional resistance to highly aggressive chemicals, making it ideal for environments where hydrocarbon, acid, and alkali exposure is routine.

PTFE’s thermal stability allows it to perform consistently in extreme temperature ranges, while its capacity to withstand significant pressure fluctuations ensures reliability in high-demand conditions. The material’s low permeability and long service life reduce maintenance frequency, making it a cost-effective choice for continuous refinery operations.

Proven Sealing Efficiency of PTFE Sealing

The superior sealing capability of PTFE sealing solutions ensures tight joint integrity under varying pressures, temperatures, and media types. Unlike many conventional gasket materials, PTFE retains its sealing properties without hardening, creeping, or degrading, even after prolonged use.

This performance is supported by compliance with established industry standards, including API, ASME, and ISO specifications for fugitive emission control. These certifications confirm that PTFE sealing solutions meet rigorous testing benchmarks, offering refineries peace of mind in critical operations.

Key Applications in Oil and Petrochemical Refineries

PTFE sealing solutions are deployed across multiple high-priority areas in refinery infrastructure:

•  Distillation units: In distillation units, PTFE sealing solutions provide reliable, leak-proof sealing even under constant thermal cycling, ensuring uninterrupted separation processes and maintaining product purity.

•  Heat exchangers: Within heat exchangers, PTFE gaskets deliver exceptional chemical resistance and maintain dimensional stability, allowing equipment to operate efficiently despite fluctuating temperatures and corrosive media.

•  Storage tanks: For storage tanks, PTFE sealing effectively prevents vapour loss and ensures the secure containment of volatile products, helping facilities comply with strict environmental and safety regulations.

•  Pipelines and process lines: In pipelines and process lines, PTFE sealing offers dependable static and dynamic sealing, enabling safe, consistent product transfer while minimising the risk of leaks or operational downtime.
