tasotiivisteet

Tasotiivisteet, often translated as gasket or seal, are mechanical components used to prevent leakage between two mating surfaces. These surfaces are typically parts of a machine or structure, such as an engine block and cylinder head, or a pipe flange. The primary function of a tasotiiviste is to maintain a seal under pressure and temperature variations, ensuring that fluids or gases are contained within their intended systems and preventing their escape into the environment.

Tasotiivisteet are made from a variety of materials, chosen based on the specific application's requirements. Common materials include rubber, silicone, cork, paper, felt, and various metals and composite materials. The selection of material is critical for the effectiveness and longevity of the seal, as it must withstand the operating conditions such as chemical exposure, heat, pressure, and vibration.

The design of a tasotiiviste can vary significantly. Some are simple flat rings, while others are more complex shapes designed to fit precisely into grooves or recesses. The method of installation also differs; some are compressed between surfaces, while others may be bonded or held in place by fasteners. The performance of a tasotiiviste is directly related to its ability to conform to the irregularities of the mating surfaces and maintain a consistent sealing force over time. Proper installation and maintenance are crucial for ensuring optimal sealing performance and preventing premature failure.
