Compression Gasket: Thickness Range 0.5mm to 6mm

Q: What is the primary function of a compression gasket in panel joint systems?

The primary function is to create a reliable seal between panel joints to prevent leakage of fluids, gases, or contaminants while accommodating thermal expansion, vibration, and surface irregularities.

Q: How do I select the right compression gasket material?

Material selection depends on operating temperature, chemical exposure, pressure requirements, compression set characteristics, and compliance standards. Common choices include EPDM for weather resistance, Nitrile for oil resistance, and graphite for high-temperature applications.

Q: What are common failure modes for compression gaskets?

Common failures include compression set (permanent deformation), chemical degradation, thermal aging, blow-out under pressure, improper installation, and incompatibility with mating surfaces or media.

Component Specifications

Definition

A compression gasket is a mechanical seal that fills the space between two or more mating surfaces in a panel joint system, typically to prevent leakage under compression. It deforms under load to conform to surface irregularities, creating a tight seal against fluids, gases, or environmental contaminants. These gaskets are engineered to maintain sealing integrity under varying pressures, temperatures, and mechanical stresses while accommodating thermal expansion and vibration.

Working Principle

The compression gasket operates on the principle of elastic or plastic deformation under applied compressive load. When installed between panel joint surfaces and tightened, the gasket material compresses to fill microscopic imperfections and gaps, creating a continuous barrier. The sealing effectiveness depends on proper compression force, material properties, surface finish, and gasket design to maintain contact stress above the system's pressure.

Materials

Common materials include: rubber compounds (EPDM, Nitrile, Silicone), compressed non-asbestos fiber (CNAF), graphite, PTFE, metal (stainless steel, copper), and composite materials. Material selection depends on temperature range (-60°C to 1000°C), chemical resistance, pressure requirements (vacuum to 300+ bar), and compliance standards.
