Rubber sheets are flat elastomeric materials used for gasketing, flooring, insulation, and lining. Bright Star offers sheets in various polymers (NBR, EPDM, Neoprene, Silicone) and hardness, suitable for industrial, electrical, and sanitary applications. Sheets are available in cloth-inserted or plain forms, and can be supplied with adhesive backing or cut-to-size upon request.
Rubber pipeline rings provide sealing and cushioning in duct pipes, joints, and manholes. They absorb expansion, reduce vibration, and prevent leakage in drainage and sewer systems. Bright Star offers rings in EPDM, NBR, and Neoprene for civil, industrial, and infrastructure applications
Rubber bellows protect moving parts from dust, dirt, moisture, and vibration. They are flexible connectors used in mechanical joints, actuators, and valves. Our bellows ensure smooth movement and extend the service life of sensitive components in automation and transport equipment. We produce both convoluted and molded types in various configurations for axial, lateral, or angular movemen
Rubber washers are flat, disc-shaped components that provide cushioning, sealing, and spacing between surfaces. These are used in plumbing, electrical, and automotive assemblies. Bright Star washers are designed to resist water, chemicals, and vibration, enhancing the longevity of joints. Our washers are also effective in noise dampening and are available in standard and non-standard dimensions for versatile application
Rubber plugs and caps are used to seal, mask, or protect components from dust, moisture, and corrosion. They are commonly used in surface finishing, powder coating, automotive, and electronics. We offer standard and custom-molded solutions in various sizes and hardness. These components are designed for easy installation and removal, and are available in high-heat-resistant and chemical-resistant formulations
Pneumatic seals operate in compressed air environments and are used in pneumatic cylinders, valves, and actuators. Unlike hydraulic seals, they are designed to function at lower pressures and require minimal lubrication. Bright Star’s pneumatic seals are known for their precision fit, low friction, and long service life in automation and machinery applications. They are ideal for dry environments and offer excellent resistance to ozone, aging, and temperature fluctuations
Canvas and Chevron seals are used in heavy-duty hydraulic applications. Chevron seals consist of a stack of multiple sealing elements that adjust to pressure variations. Canvas seals, made from rubber-coated fabric, offer enhanced pressure resistance. These seals are widely used in press machines, earth-moving equipment, and mining systems. Bright Star offers customized V-packings and fabric-reinforced seals for high-pressure systems needing excellent flexibility and sealing capability
Rubber parts like seals, washers, and mounts are essential in tractors, sprayers, irrigation pumps, and tillage equipment. These components help absorb vibration and withstand outdoor weather and chemicals. Our agricultural-grade rubber components ensure operational reliability, UV resistance, and compatibility with fertilizers and pesticides.
Rubber stoppers are used to seal glass vials, infusion bottles, and reagent containers. These are manufactured in pharmaceutical-grade rubber and tested for biocompatibility and extractables. We offer sterilizable formulations and customized designs to support aseptic packaging and long shelf life
Rubber diaphragms are flexible membranes used to separate two chambers while transferring pressure or movement. Commonly found in pumps, valves, and regulators, they must offer consistent elasticity and chemical resistance. Bright Star manufactures diaphragms for precise performance and long service life. Our diaphragms are engineered for dynamic response, low permeation, and resistance to aggressive media such as acids, solvents, and gases.
Rubber gaskets provide a reliable seal between two surfaces in static applications. Bright Star manufactures gaskets from NBR, EPDM, Silicone, and Neoprene for applications in water pipelines, HVAC systems, and flanged joints. They offer excellent compressibility, resilience, and resistance to weathering. We offer precision die-cut and custom-molded gaskets that conform to a variety of surface geometries, even under high pressure and fluctuating temperatures.
Rubber seals are used to fill gaps between two surfaces and prevent fluid leakage, dust ingress, or vibrations. These include lip seals, shaft seals, and radial seals made from materials such as NBR, Viton, and Silicone. Our seals ensure durability and chemical resistance in harsh working conditions, serving key sectors like automotive, appliances, and heavy machinery. We offer custom-molded and standard seal designs that can withstand a wide range of temperatures and media, ensuring long-term performance.
