Gasket

Rubber gaskets are die-cut or molded from premium rubber materials, including NR, EPDM, NBR and FKM. As sealing accessories between flanges and pipe connectors, they are placed between two mating surfaces. When bolts are tightened, the gaskets deform elastically to fill gaps and prevent medium leakage. Different materials deliver different properties: EPDM features good water resistance, aging resistance and acid-alkali resistance for water supply and sewage; NBR is oil-resistant for oil-containing media; FKM withstands high temperature and strong corrosion. Available in a full range of sizes to match various flanges, rubber joints and pipe connectors. With stable sealing performance and easy replacement, rubber gaskets are widely used in municipal water supply, sewage treatment, chemical, power and oil-gas pipeline systems.

Rubber gaskets are essential sealing components for pipeline flange connections. Made of high-quality elastic rubber via high-temperature molding and precision cutting, they feature uniform texture, superior resilience and stable sealing performance. Available in

NR, EPDM, NBR and FKM materials, the gaskets suit diverse media, temperatures and working conditions. Installed between flanges,

pipe connectors and rubber joints, they form tight seals through elastic deformation under bolt compression, effectively preventing liquid

and gas leakage. They also cushion minor pipeline vibration and displacement, ensuring safe and stable operation of pipeline systems.

Different rubber materials deliver targeted performance: EPDM gaskets excel in water resistance, aging resistance and acid-base resistance, ideal for municipal water supply, drainage, sewage treatment and landscape irrigation. NBR gaskets with excellent oil

resistance are applicable for oil and gas medium pipelines. FKM gaskets resist high temperature and strong corrosion, perfect for

chemical and high-temperature working scenarios. NR gaskets feature high cost performance and elasticity for conventional clean

water pipelines.All gaskets adopt standard sizes with uniform thickness, complying with GB, ASME, DIN standards, and compatible with

welded flanges, PE flanges, universal flange adaptors and various pipe fittings.Featuring stable structure, great compression resilience

and outstanding aging and wear resistance, these gaskets resist deformation and cracking under long-term pressure for a long

service life. They are easy to install and replace without complicated construction, reducing pipeline maintenance costs. Widely used in

municipal water projects, fire protection, chemical industry, electric power, oil and gas, construction and other industrial and civil pipeline

systems, they are reliable and versatile sealing accessories for pipeline engineering.
