Tiivisteköysi

Tiivisteköysi, known in English as sealing rope or gasket cord, is a flexible material used to create seals between surfaces, preventing the leakage of gases or liquids. It is typically made from fibrous materials such as graphite, ceramic, or fiberglass, often impregnated with binders or lubricants to enhance its sealing properties and durability. The construction of tiivisteköysi can vary, including braided, knitted, or twisted forms, each offering different characteristics suitable for specific applications. Braided ropes are common for their resilience and ability to conform to irregular surfaces, while knitted versions might offer greater compressibility.

The primary function of tiivisteköysi is to provide a tight seal in applications where rigid gaskets are impractical or would fail due to thermal expansion and contraction, vibration, or pressure fluctuations. It is widely employed in industrial settings, particularly in high-temperature or high-pressure environments. Common uses include sealing furnace doors, oven openings, boiler manholes, and pipe flanges. It can also be found in automotive engines, exhaust systems, and marine applications. The material's resistance to heat, chemicals, and abrasion makes it a versatile choice for demanding sealing tasks. Installation often involves cutting the rope to the required length and fitting it into a groove or recess designed to hold it in place. The compressibility of the rope allows it to fill gaps and create a leak-proof barrier when the sealed components are brought together.
