In chemical processing, refining, oil and gas, and power generation, a gasket is a critical part of the fluid-sealing system. Aggressive chemicals, hydrocarbons, caustics, solvents, elevated temperatures and changing process conditions can challenge sealing reliability. Selecting the right chemical-resistant gasket material helps reduce leakage risk, extend service life and support reliable plant operation.
Hanna Rubber provides a solution that combines high-performance gasket materials from trusted manufacturers with in-house custom gasket fabrication, material expertise and responsive industrial service.
Chemical Resistance Is Critical to Industrial Gasket Performance
Gasket selection becomes more complex when process media can attack or degrade sealing materials. Chemical compatibility is only one consideration. Engineers and maintenance teams must also evaluate operating temperature, pressure, chemical concentration, flange condition, available bolt load and the demands of the specific application.
These considerations are particularly important in:
- Chemical processing equipment and piping
- Refinery process systems
- Oil and gas production and processing
- Petrochemical facilities
- Power generation equipment
- Pumps, valves and pressure vessels
- Heat exchangers and process piping
- Storage and transfer systems
Using an improperly matched gasket can contribute to premature deterioration, leakage, maintenance requirements and unplanned downtime.
The solution is not simply a more expensive gasket—it is the right gasket material, fabricated correctly for the application.

Garlock, GYLON PTFE, BLUE-GARD and Durlon Gasket Materials
Hanna Rubber gives industrial customers access to multiple gasket-material technologies, allowing the sealing solution to be matched more closely to the media and operating conditions.
GYLON® PTFE Gasket Materials
Garlock GYLON® gasket materials provide an important option for demanding chemical applications. Garlock’s engineered PTFE technology is designed to improve performance compared with conventional PTFE, including reduced creep relaxation and cold-flow concerns while maintaining broad chemical resistance.
Depending on the specific GYLON style selected, applications can include acids, caustics, hydrocarbons, solvents, chlorine and other aggressive process media.
That makes GYLON particularly relevant for chemical processing, refining, oil and gas and power-generation applications involving:
- Piping systems
- Pumps
- Pressure vessels
- Scrubber systems
- Storage tanks
- Chemical reactors
- Heat exchangers
- Process equipment
Garlock BLUE-GARD® Gasket Materials
Garlock BLUE-GARD® compressed gasket materials combine aramid fibers, fillers and elastomeric binders to provide dependable sealing performance across a wide range of industrial services.
BLUE-GARD materials are available in multiple styles, enabling users to select gasketing based on the application’s media, temperature, pressure and compliance requirements. The material family is also engineered for torque retention and easier gasket removal, helping support efficient maintenance.
For applications where compressed fiber gasketing is appropriate, BLUE-GARD can provide an effective balance of sealing performance, durability and operating economy.
Durlon® Gasket Materials
Durlon offers both compressed non-asbestos and PTFE gasket technologies for industrial sealing applications.
For aggressive chemical service, Durlon 9000 filled PTFE is specifically designed for general industrial applications requiring resistance to highly aggressive chemicals. Its applications span chemical processing, oil and gas, petrochemical operations, power generation and refining.
Durlon’s broader portfolio also allows gasket selection to be matched to different combinations of media, pressure and temperature rather than relying on one material for every sealing point.
Important: Chemical compatibility varies with the specific fluid, concentration, pressure, temperature and application. Material compatibility should always be verified before installation.
Key Benefits and Applications of Chemical-Resistant Gasket Materials
Selecting the appropriate Garlock, GYLON, BLUE-GARD or Durlon material can help industrial facilities:
- Improve chemical resistance: Match gasket construction to acids, caustics, solvents, hydrocarbons and other process media.
- Reduce leakage risk: Proper material selection and precision fabrication support more reliable flange sealing.
- Improve gasket service life: Chemical compatibility can reduce premature material deterioration.
- Support demanding process equipment: Solutions are available for pumps, valves, piping, vessels, tanks, heat exchangers and other equipment.
- Address PTFE cold-flow concerns: Engineered PTFE products such as GYLON are designed to reduce creep relaxation compared with conventional PTFE.
- Improve maintenance efficiency: Properly specified gasket materials can reduce replacement frequency and help simplify planned maintenance.
- Serve multiple process industries: Options are available for chemical processing, refining, petrochemical, oil and gas and power-generation environments.
Why Choose Hanna Rubber for Industrial Gasket Solutions?
Finding the right gasket sheet is only part of the solution. Hanna Rubber combines gasket material availability with precision fabrication and industrial application support.
Hanna Rubber stocks gasket materials including compressed fiber, carbon, graphite and PTFE sheet in standard thicknesses and offers extensive custom fabrication capabilities.
Need finished gaskets instead of sheet material? Hanna Rubber can manufacture custom gaskets from drawings, patterns and application requirements. Available processes include die cutting, waterjet cutting and other precision cutting technologies for prototypes through production quantities.
Waterjet cutting is especially valuable for complex PTFE and non-metallic gaskets because it is a cold-cutting process. This helps preserve material properties while producing intricate shapes and tight tolerances without dedicated tooling.
For maintenance teams, MRO buyers and engineers, that means one supplier can help solve multiple parts of the gasket requirement:
Material selection → stocked gasket sheet → precision fabrication → finished custom gasket → responsive delivery.

Frequently Asked Questions About Chemical-Resistant Gasket Materials
What gasket material is best for aggressive chemicals?
The best gasket depends on the specific chemical, concentration, operating temperature, pressure and flange conditions. Engineered PTFE materials such as Garlock GYLON and Durlon PTFE products are strong candidates for many aggressive chemical services because of their broad chemical resistance. Always verify compatibility for the specific operating conditions.
What is the difference between GYLON PTFE and BLUE-GARD gasket material?
GYLON is Garlock’s engineered PTFE gasket technology and is frequently selected where broad chemical resistance is a priority. BLUE-GARD is an aramid-fiber compressed gasket material available in multiple styles for a range of industrial sealing services. Selection should be based on media, temperature, pressure, flange design and application requirements.
Are Durlon gaskets suitable for chemical processing and refining?
Yes, specific Durlon materials are designed for these markets. For example, Durlon 9000 filled PTFE is intended for general industrial applications requiring resistance to highly aggressive chemicals and is positioned for chemical processing, oil and gas, petrochemical, power-generation and refining applications. The specific grade must still be verified against actual operating conditions.
Can Hanna Rubber fabricate custom Garlock, PTFE and industrial gaskets?
Hanna Rubber offers custom gasket fabrication using multiple cutting technologies, including die cutting and precision waterjet cutting. Gaskets can be produced from drawings, patterns or samples for applications ranging from prototypes and replacement parts to production quantities.
