Bellows
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 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 droppers form the squeezing part of liquid dispensing systems. Used in syrups and eye drops, they are made from medical-grade elastomers to ensure purity and elasticity. Bright Star produces droppers in various sizes, colors, and durometers to meet branding and dosage accuracy requirements.
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.
Bright Star manufactures high-purity rubber components that meet pharmaceutical standards. We ensure compliance with FDA, USP Class VI, and ISO 10993. Our products are designed for single-use and repeated-use applications in drug delivery systems, diagnostic equipment, and biotech processing lines
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
Rubber bushes absorb shock and reduce noise and vibration between metal parts. They are used in suspension systems, engine mounts, and industrial machinery. Our bushes are made from high-durability elastomers to withstand heavy loads and environmental stresses. Bright Star offers cylindrical, flanged, and bonded bushes to meet specific mechanical performance requirements.
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
These rubber parts are formulated with carbon or conductive fillers to safely dissipate static electricity. They are critical in electronics, explosive environments, and cleanroom operations. Bright Star’s anti-static components meet ESD and EMI standards. Our product line includes conductive mats, tubing, seals, and gaskets tailored to sensitive electronic assemblies and volatile handling areas
Hydraulic seals are critical for maintaining pressure in hydraulic cylinders and preventing fluid leaks. These include piston seals, rod seals, wipers, and guide rings designed to handle high pressure and dynamic motion. Manufactured using wear-resistant materials, Bright Star’s hydraulic seals serve industries such as construction, agriculture, and manufacturing. They are developed to endure extreme forces, resist extrusion, and function reliably in high-speed or high-load applications
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
