Like any device that is installed incorrectly or is subjected to high stress, O-rings are susceptible to failure. O-rings made of different materials have different service lives.

Physical character: Braided of PTFE yarn fiber, PTFE filament add graphite particles, anti-corrosive lubricant, aramid fiber with almost complete chemical inertia, dimensional stability, low friction coefficient to compression, and excellent resistance to

Acrylic packing is woven from high-strength acrylic synthetic fibers, pre-impregnated with PTFE, and re-impregnated with PTFE emulsion during the weaving process. It can contain oil or not, and it can be impregnated with graphite.

Braided from high quality Aramid fiber with PTFE Impregnation and lubricant additive. Extremely hard wearing. It shows good chemical resistance, high elasticity and very low cold flow.

​PTFE gaskets are used in services where it is necessary to have a high chemical resistance. As with any fluid sealing material there is some overlapping of the individual products. Several materials can be used successfully in the same application.

A polymer with exceptional chemical resistance, Polytetrafluoroethylene (PTFE), is the most widely used plastic for industrial sealing.

PTFE sheet is a versatile material known for its excellent properties and wide range of applications. PTFE, which stands for polytetrafluoroethylene, is a synthetic fluoropolymer of tetrafluoroethylene.

​Ceramic Fiber Blanket Insulation is manufactured from spun ceramic fiber and is needled to provide exceptional handling strength for high-temperature insulation applications.

PTFE packing is woven by pure PTFE fiber through knitting equipment and is not treated with PTFE emulsion and lubricating grease.

​Graphite packing is mainly made of various reinforcing fibers, metal wires (steel wire, copper wire, nickel wire, carbon fiber, pre-oxidized wire, glass yarn) and other reinforced graphite wires as raw materials.

​Flexible graphite packing is a flexible packing made of selected high quality natural flake graphite, after acidification, expanded and twist. It has chemically resistant, self-lubricating, excellent high temperature capability and thermal conductivity.

Natural graphite is formed by the transformation of carbon-rich organic matter under the long-term action of high temperature and high pressure geological environment.

Expanded PTFE sealing tape has excellent corrosion resistance, self-lubricating properties, good flexibility, and high and low temperature resistance. The back of the sealing tape is coated with adhesive for easy use.

​Packing is braided yarn made from a variety of materials such as graphite, aramid, and PTFE. Many braided packings will also incorporate blocking agents and other coatings to minimize leakage through them and provide cooling and lubrication during startu

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.

THE METALLIC RING TYPE JOINT IS USED IN THE PETROLEUM INDUSTRY, WHERE HIGH PRESSURE APPLICATIONS NECESSITATE THE NEED FOR A HIGH INTEGRITY SEAL.

​Non-Asbestos Fibre materials are so-called because they fill the gap in the range of gasket materials previously occupied by asbestos.

Metal winding gasket is a sealing element is important, is widely used in petroleum, chemical,metallurgy, electric power, shipbuilding and other industries
