The vulcanized fibre sealing washer provides reliable sealing for screwed joints and threaded connections. Made from a high-quality cellulose-based fibre composite, it combines high mechanical strength, dimensional stability and low weight. At the same time, the sealing washer protects sensitive surfaces and also provides electrical insulation.
Vulcanized fibre sealing washers are temperature-resistant up to approximately 120 °C and resistant to oils, greases and many solvents. The material is electrically non-conductive, corrosion-resistant and helps reduce vibration and noise in screwed joints. Thanks to their high compressive strength, vulcanized fibre sealing washers provide long-lasting, reliable sealing performance.
Vulcanized fibre sealing washers are used wherever screwed joints require reliable sealing. Typical applications include the heating, plumbing and installation industries, as well as valve, fitting, machinery and equipment manufacturing. They are also suitable for electrical applications where both sealing and electrical insulation are required. When used as plain washers, they protect sensitive surfaces and help reduce vibration and noise.
