Ceramic Graphite Seals

Marys carbon custom manufactures a variety of seals grades to suit any application.

Ceramic graphite seals.

The inconel wire reinforcement in these expanded graphite yarn seals ensures they keep their shape longer than the high flexibility steam resistant packing seals. They resist acids. It is soft and can be easily laminated to form thicker seals.

All of our seals from the blending of raw materials to the finished product are made in house by our. Carbon graphite mechanical seal rings. Its superiority to the fine ceramic materials currently under the spot light of today s leading edge technology is also confirmed by its outstanding high temperature high purity and low gas. Graphite specialty carbon has many special features of which properties clearly indicate its superiority to metal materials such as copper or iron.

Ceratex 3120 ceramic fiber tape is a narrow woven fabric manufactured from high temperature alumino silicate based ceramic fiber reinforced with high temperature fiberglass. The product is white and odorless suitable for high temperature applications up to 2300 f. Alumina silicate is loosely woven to create these ceramic seals that are stronger and more flexible than ultra high and low temperature rope seals. A ceramic cover makes these seals more chemical resistant than the seals with a silica cover.

Pure carbon graphite is strictly speaking a ceramic material but in the form that it is used for seals it will usually be impregnated with other materials that are provided to variously improve the sealing. We offer blank stock various impregnations and have the capability to machine intricate seals with polished faces. By reducing porosity wear performance or strength is increased. The inconel wire reinforcement in these expanded graphite yarn seals ensures they keep their shape longer than the high flexibility steam resistant packing seals.
