The O-rings may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. They can seal tens of megapascals (thousands of psi) of pressure.
The gasket are made of a reinforced graphite sheet or non asbestos sheet by punching or pressing, depend on its excedllent corrosion-resistance, high-and-low temperature resistance, finecompression resilient the product is widely applied as cylinder head seals of automobile engine, diesel engine, air compressor, refrigerating machine, etc.
Rubber gaskets are cut from rubber sheets or mould pressing
Asbestos rubber gasket or non-asbestos gasket is made from asbestos fiber or aramid and other organic fiber, vegetable fibre, NBR rubber and assisted with rubber accessory ingredient and filing through mixing, hot-roller molding and sulfuration. It is divided into commonr gasket and oil-resistant gasket according to its prescription, technology, performance and use. It is suitable for water, steam, oil, solvent, medium acid and alkaline sealing. We also use other gasket material like Klinger, Garlock, Valqua, Gore, Frenzelit and so on Technical Parameter
PTFE Envelope Gasket is compounded with the soft asbestos rubber sheet, non-asbestos sheet, rubber or graphite reinforcement plate as filler, and wrapped with PTFE. With excellent corrosion resistance and good compression and resilience rate, it is widely applied for sealing of strong acid, strong alkali, strong oxidizer, chlorine and contamination-free mediums.
Composite gasket of cladding other non-metal metal with PTFE, which does not only have the chemistry repellence performance of PTFE, but also have good tensile performance due to its core materials. It is indispensable in chemical industry and chemical devices.
