A Die-formed Ring is a type of packing ring made of expanded graphite without any filler or binders. Its construction allows for an extremely precise and efficient seal. It is available in various densities and sizes. A Die-formed Ring has several advantages over other packing ring materials.

Graphite Die-formed Rings are used in a wide range of applications. These packing rings are extremely durable and can withstand high temperatures. They are suitable for valve stem packing, stuffing box packing and for many other applications. They are also suitable for cryogenic conditions. These properties allow them to work in a wide range of chemical products and are fire safe.

Graphite Die-formed Rings can significantly reduce the torque needed for efficient valve action. They can also help to reduce the power consumption of the actuators used in valves. Graphite Die-formed Rings have exceptionally low break-out friction and can maintain this extremely low friction for up to 20,000 valve cycles. Manual adjustment of the rings can further extend their service life.

Graphite Die-formed Rings are made from high purity flexible graphite foil. Graphite die-formed rings are ideal for valve stem packing and have an excellent compression coefficient. They can also be manufactured with metal end caps. They are excellent for sealing applications that require high pressure and can withstand high temperatures.
