One prominent example is the use of elastic metal seals (C-rings) in the aviation industry for the production of PD-14 aircraft engines, used in the domestic MS-21 airliner, as well as in PD-8 engines for the "Superjet" SJ-100 and PS-90A1 for the Il-96-400T.

Oleg Isaev, General Director of Silur LLC, noted that the company produces not only a wide range of seals made of thermally expanded graphite, but also new types of seals made of special alloys with various coatings for different industries.

We implement a comprehensive approach to sealing, selection/development, design, manufacturing, and supervision. In addition, we are the only ones on the market who offer a service – "mobile units" – that allows us to perform sealing work directly at the equipment's operating location.

Earlier, www1.ru reported that a Major General of Aviation called the plans to build 100 MS-21 aircraft by 2030 unrealistic.
