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