Asbestos Non Asbestos Gasket For Level Gauge Graphite PTFE cushion

1）Asbestos Sealing Gaskets for gauge glass is also named asbestos cushion or asbestos cushion joint, they are made from high pressure compressed asbestos fibre rubber sheets resistant to temperatures up to 450 °C and the pressure to 150 bar.
Asbestos gaskets is a traditional material for the gauge glass sealing,which is a general purpose gasket material suitable for service in hot water, mild acids, alkalines, and inert gases. Now most of western countries ban the use of asbestos products, but in some developing countries, this product is still used in large quantities.

2）Graphite gasket for level gauge is also named graphite sealing gasket which resistant to temperatures up to 450 °C and the pressure to 150 bar.There are two types of graphite sealing gasket：

3) Non asbestos cushion for gauge glass is also named non asbestos gasket or cushion joint, which is made of high pressure Aramid fiber mixed rubber sheets resistant to temperatures up to 450 °C and the pressure to 150 bar.

Non asbestos cushion is a new material for the gauge glass sealing as a general purpose gasket material suitable for service in hot water, mild acids, alkalines, and inert gases in some countries baned the use of asbestos gasket.

4)PTFE is a special plastic which has excellent non-stick properties, that means most of substance can not adhere on its surface. PTFE is not affected by almost all chemicals and solvents and has outstanding dielectric properties, making PTFE sheets the ideal engineering plastic for electrical and thermal insulators,seals,glide ringds,etc. PTFE also has excellent UV resistance and is capable of continuous use at -80- 260 Deg.C.
