Paper Gaskets – When to Use Them?
What Are Gaskets?
Gaskets are specially designed components placed between two or more mating surfaces to prevent unwanted leaks when compressed and to ensure system integrity and performance. Depending on the application, they can be made from various materials: metallic, non-metallic, or semi-metallic. Choosing the right gasket material is essential for proper function, especially under demanding conditions.
Among the most common gasket materials are rubber, paper, and compressed non-asbestos fibre (CNAF). Each material offers unique physical and mechanical properties, such as resistance to extreme temperatures, pressure differences, or aggressive chemicals and fuels, tailored to specific applications.
What Are Paper Gaskets?
Paper gaskets are made from compressed sheets of cellulose, silicone rubber, nitrile rubber, cork, or similar flexible materials. Known for their ability to conform to uneven surfaces, they create airtight and watertight seals between components in machines and equipment. They offer reliable sealing performance and effectively prevent leaks.
Gasket paper can be cut into custom shapes and sizes. Rubber gasket sheets are the most common due to their flexibility and tolerance to temperature and pressure fluctuations.
However, paper gaskets are not suitable for high-temperature or high-pressure environments, or for use with aggressive chemicals and solvents that could compromise their integrity.
Advantages and Properties of Paper Gaskets
Due to their versatility, paper gaskets are widely used across various industries. They deliver dependable sealing performance in applications involving water, most fuels, oils, and chemicals. Gasket paper is a cost-effective yet efficient and reliable solution, easily produced in various shapes and sizes.
Proper installation and torque control are crucial for effective sealing. Thanks to their flatness and compressibility, paper gaskets adapt to uneven or rough surfaces, maintaining a tight seal even in industrial conditions. Depending on the paper type, they may also offer insulation properties and be environmentally friendly.
When to Use Paper Gaskets?
The choice of gasket material must align with working conditions. Paper gaskets are suitable for moderate temperatures, low to medium pressures, and where the medium does not degrade the paper. They are ideal for household appliances and light industrial machinery.
Applications of Paper Gaskets
Paper gaskets are widely used in the automotive, aerospace, marine, and construction sectors. They’re also common in household appliances (fridges, air conditioners) and industrial machinery.
Typical uses include:
-
Oil pans in vehicles
-
Exhaust systems
-
Gearboxes
-
Vehicle water pumps
-
Valve covers
-
Aircraft fuel and hydraulic systems
-
Plumbing (valves, taps, pipes)
-
Pump housings and covers
-
Engine cylinder heads
-
HVAC duct connections (heating, ventilation, air conditioning)

Installation and Maintenance Tips
Proper installation and maintenance are vital for longevity and leak prevention. Follow these steps:
-
Choose compatible paper – match it with the operating environment (fluids, temperature, pressure).
-
Clean surfaces – remove old gasket remains, degrease and smooth the surface.
-
Ensure proper sizing – we offer guidance at Power Rubber to help you select the right gasket.
-
Correct torque – excessive or insufficient tightening can damage the gasket or reduce sealing effectiveness.
-
Use sealant or adhesive if required – in some cases, this improves sealing reliability.
-
Regular inspections – check for degradation or damage; replace if necessary.
Avoid reusing old gaskets. Always store new ones in a dry, cool environment.
