Various Colors NBR Rubber Ring For Sealing

All our colored NBR rings are made of qualified nitrile butadiene rubber as the base material. We adopt fixed rubber compound ratios for different color grades, with color pigments added in strict proportional control during internal mixing. The coloring process does not change the original physical and chemical properties of NBR materials, ensuring each colored batch maintains unified hardness, elasticity and compression resistance. Common colors include black, red, blue, green and transparent tinted styles, which mainly serve as intuitive identification marks for different equipment circuits, working pressure levels or equipment maintenance distinctions.

NBR rubber rings feature stable basic sealing performance suitable for conventional industrial working conditions. The material delivers good oil resistance, wear resistance and air tightness, adapting to long-term contact with hydraulic oil, lubricating oil, gasoline and conventional industrial water media. Under normal working temperature ranging from -40°C to 120°C, these rubber rings can maintain stable elasticity, avoiding frequent aging, deformation and sealing failure caused by medium erosion and temperature change.

In production management, we complete rubber mixing, high-temperature molding, vulcanization and trimming in standardized workshops. The secondary vulcanization process is adopted to eliminate internal stress of rubber materials, effectively improving product durability and reducing shrinkage rate. All finished products are processed with smooth surface treatment to ensure tight fitting with grooves and prevent leakage caused by surface burrs or dimensional deviation. We conduct regular sampling inspection on material hardness, tensile strength and compression resilience to guarantee batch stability.

We support customized size and color production for non-standard working conditions. Conventional O-rings, flat rubber sealing rings and special-shaped NBR sealing parts can be processed according to customer drawings and parameter requirements. All customized products follow the same factory inspection standards as standard parts to ensure uniform quality.

Widely applied in mechanical equipment, hydraulic systems, automotive parts, electrical appliances and general industrial pipeline sealing, our multi-color NBR rubber rings rely on stable quality and clear color classification to simplify equipment assembly and daily maintenance, providing cost-effective conventional sealing solutions for industrial customers.
