  The Gaskets of a perfectly new concept.
Self-energized Seal Style.
Max. Temperature: 700℃, Max. Pressure: 310 bar.

YL#7700 Graphite Pressure Seal Gaskets is a Gaskets of perfectly new concept. It is self energized seal style, and it is used to high temperature and high pressure which are over 600PSI valves. It is usually used to atomic generation, steam generation, and pertochemistry.
Originally used materials of Metal are not adapted well to irregular and transformed valve which is made by high temperature and high pressure as generation gets old. We make a product using flexible, elastic, and restorable Graphite and end cap.
YL#7700 Graphite Pressure Seal Gaskets uses materials which are managed by corrosion inhibitor and expanded graphite having high degree of purity. It is very flexible, elastic, and restorable. After perfectly correcting deformities, we put end cap in it. The product is well adapted to irregular and transformed valve which is made by high temperature and high pressure.


It can be easily corrected to the same shape like the shape of fabricated valve body and bonnet.
It is very easy to put in and take out without harming the body of valve.
In case of harming the surface of sealing, you can reduce the cost of preservation and repair because it is very easy to correct deformities by its flexibility, elastic ability, and restorable ability.
The life of high pressure valve can be lasted for long time because corrosion inhibitor is used to Graphite.
