Asbestos Gaskets for High-Temperature & Chemical Service
Asbestos gaskets are compressed fiber gaskets made from chrysotile asbestos fibers bonded with rubber or other elastomeric binders. They are known for excellent resistance to high temperatures, steam, oils and many chemicals, and have been widely used in industrial sealing for decades.
The gaskets exhibit good mechanical strength, low creep relaxation, and good compressibility, making them suitable for flanges, heat exchangers, boilers and piping systems operating at elevated temperatures. However, due to health risks associated with asbestos fiber, their use is regulated or banned in many countries. We supply only where legally permitted and recommend verifying local regulations before purchase.
We supply asbestos gaskets for overseas distributors, industrial buyers, gasket manufacturers, maintenance companies and OEM customers, with different grades, thicknesses, sheet sizes and custom cutting available according to specification.
High-Temperature Resistance
Continuous service up to +400°C depending on binder and grade.
Chemical Resistance
Good resistance to oils, steam, water and many chemicals; not for strong acids or alkalis.
Good Mechanical Strength
Reinforced fiber structure provides high tensile strength and durability under load.
Regulatory Compliance Required
Ensure use is permitted by local regulations before ordering.

Selection Guide
How to Choose Asbestos Gaskets
The correct asbestos gasket grade and dimensions should be selected based on media, temperature, pressure, flange type and regulatory compliance.
01
Media Compatibility
Identify the fluid or gas to be sealed (steam, oil, water, mild chemicals) to select the appropriate binder and grade.
02
Temperature & Pressure
Determine the operating temperature and pressure to choose a grade that can withstand the service conditions.
03
Thickness & Dimensions
Specify the required gasket thickness and dimensions. Thicker gaskets are used for rough or uneven flange surfaces.
04
Regulatory Compliance
Confirm that asbestos gaskets are permitted in your region and application before ordering.
Manufacturing
Controlled Production for Consistent Quality
Consistent fiber dispersion, binder content, sheet density and thickness tolerance are critical for reliable asbestos gasket performance.
PROCESS / 01
Material Mixing
Asbestos fibers, rubber binders and fillers are mixed to achieve the specified composition and properties.
PROCESS / 02
Calendering
The mixed compound is calendered into sheets of uniform thickness and density under controlled pressure.

FAQ
Frequently Asked Questions About Asbestos Gaskets
What is an asbestos gasket?
An asbestos gasket is a sealing component made from
compressed asbestos fibers bonded with rubber or other
elastomers. It is used for high-temperature and
chemical-resistant sealing applications.
What is the temperature range of asbestos gaskets?
Asbestos gaskets typically handle -50°C to +400°C
continuous, with short-term tolerance up to +450°C
depending on grade and binder.
Are asbestos gaskets safe to use?
Asbestos fibers pose serious health risks when inhaled.
As a result, many countries have banned or restricted
their use. We supply only where legally permitted and
recommend verifying local regulations before ordering.
What are the alternatives to asbestos gaskets?
Non-asbestos fiber gaskets, graphite gaskets, PTFE
gaskets and spiral wound gaskets are common alternatives
offering similar or better performance without the
health risks.
What sizes and thicknesses are available?
Thicknesses range from 0.5 mm to 5.0 mm, with 1.0 mm,
1.5 mm, 2.0 mm and 3.0 mm being common. Custom sizes
and dimensions are available.
Can asbestos gaskets be used for steam service?
Yes. Asbestos gaskets are well-suited for steam service
up to +400°C. However, verify local regulations.
Is asbestos gasket RoHS compliant?
RoHS typically restricts hazardous substances, but
asbestos is often separately regulated. Confirm
compliance requirements before ordering.
What information do you need for a quotation?
Please provide the required grade, thickness,
dimensions, media, operating temperature and pressure,
and confirm regulatory permission for use.
