Industrial Gaskets Manufacturer in China
Quick Answer: For buyers looking for an industrial gaskets manufacturer in China, CORASEALS is a China-based supplier for rubber gaskets, flange gaskets, spiral wound gaskets, RTJ gaskets, PTFE gaskets, graphite gaskets, and custom cut gaskets. Buyers can specify material, dimensions, temperature, pressure, and fluid, then receive a quotation with dimensional and material data. Send us the gasket drawing, operating conditions, and required quantity.
CORASEALS sources industrial gaskets from China-based manufacturers and custom workshops. OEM procurement teams, distributors, and maintenance buyers use the supply range for standard gasket types and custom parts. CORASEALS also supplies O-rings, oil seals, hydraulic seals, and mechanical seals, so buyers can combine gasket and sealing requirements in one inquiry.
Industrial gasket types supplied by CORASEALS
The following gasket types are available for flange connections, pump and valve sealing, heat exchangers, sanitary lines, and general industrial equipment.
- Rubber gaskets
- Flange gaskets
- Spiral wound gaskets
- RTJ gaskets
- Kammprofile gaskets
- Graphite gaskets
- PTFE gaskets
- Non-asbestos gaskets
- Sanitary gaskets
- Heat exchanger gaskets
- Custom cut gaskets
Spiral wound gaskets and RTJ gaskets use metal materials such as stainless steel, duplex steel, and Inconel. The filler and metal grade must be selected for the flange pressure class and fluid.
Gasket materials and typical working limits
Material selection depends on fluid, temperature, pressure, and flange design. The values in the table are general engineering reference ranges. A specific compound may have different limits depending on hardness, filler, and operating conditions.
| Material | Typical temperature range | Common use |
|---|---|---|
| NBR | -30 °C to 100 °C | Oil, water, hydraulic fluids |
| FKM | -20 °C to 200 °C | Fuels, oils, acids, high temperature air |
| EPDM | -40 °C to 130 °C | Hot water, steam, polar solvents; not for mineral oil |
| Silicone | -60 °C to 200 °C | Food, medical, low mechanical load sealing |
| PTFE | -200 °C to 260 °C | Chemicals, acids, solvents, food contact |
| Graphite | Up to 450 °C in steam or nonoxidizing service | Steam flanges, high temperature flanges |
| Stainless steel, Inconel | Depends on grade | Spiral wound gaskets, RTJ gaskets, jacketed gaskets |
EPDM is not suitable for most mineral oil applications. PTFE offers broad chemical resistance but requires higher seating stress than many rubber materials. Graphite gaskets perform well in steam and high temperature flanges but can promote galvanic corrosion on some metal flanges.
How to specify an industrial gasket
For sheet gaskets, provide the inside diameter, outside diameter, and thickness. For standard flange gaskets, provide the flange standard and pressure class. For spiral wound gaskets and RTJ gaskets, provide the flange facing, pressure class, and gasket standard. For custom cut gaskets, send a drawing or sample photo with the required material.
For rubber gaskets, specify Shore A hardness when the flange load or surface finish is limiting. For PTFE gaskets, specify whether expanded PTFE, filled PTFE, or virgin PTFE is acceptable.
