As a dedicated supplier of sealing solutions, I offer high-quality Rubber O-ring crafted for demanding OEM projects and important for any Suppliers' chain. Our Rubber O-ring delivers consistent performance in hydraulic, pneumatic, and fluid systems, resisting compression set, temperature swings, and chemical exposure. I work directly with OEM engineering teams to select compound types—Nitrile, FKM, silicone—based on media, temperature and load. For Suppliers, I provide scalable inventories, quick lead times, and ready-to-ship sizes from stock or custom molds. The dimensions are tight to ISO tolerances, and the surface finishes minimize leakage risks. I ensure traceable material certificates, testing data, and compliant packaging. Partner with me to streamline procurement, reduce downtime, and extend equipment life with dependable Rubber O-ring solutions.
Global buyers seek seals they can trust. A factory-direct supply of rubber O-rings delivers competitive pricing, shorter lead times, and consistent quality by removing middlemen. Standard elastomers cover NBR, EPDM, FKM, and silicone, with a wide range of sizes and profiles—from micro rings to larger seals. Durometers from 50 to 90 Shore A suit varied fluids and temperatures. Backed by engineering expertise, we offer material selection guidance, OEM spec reproduction, and design-for-manufacture input to optimize fit and performance. In-house testing and strict QC ensure accuracy and leak resistance. Documentation includes material certificates, test reports, and batch traceability for compliance. Partnering with a factory-direct supplier means scalable production, flexible MOQs, and dependable on-time delivery for global sites. We tailor packaging, labeling, and logistics to regional needs, with responsive support to handle substitutions and post-delivery service, ensuring seals perform in demanding environments worldwide.
| Material | Shore Hardness (A) | Typical Applications | Temperature Range (°C) | Chemical Compatibility (summary) | Manufacturing Methods | Dimensional Tolerance (typ.) |
|---|---|---|---|---|---|---|
| Nitrile (NBR) | 60–90 A (commonly 70 A) | Hydraulic seals, fuel systems, general-purpose oil seals | -35 to 120 | Good: mineral oils, fuels. Poor: ketones, some esters, ozone | Injection & compression molding, CNC lathe-cut | Typical ±0.05–±0.20 mm (size & cross-section dependent) |
| EPDM | 60–90 A | Water/steam seals, brake systems, HVAC, outdoor weather seals | -50 to 150 | Good: water, steam, polar solvents, acids. Poor: petrol/oils, hydrocarbons | Compression & injection molding, extrusion | Typical ±0.05–±0.25 mm |
| Fluoroelastomer (FKM) | 70–90 A | High-temperature seals, fuel systems, chemical processing | -20 to 200 | Excellent: oils, fuels, many solvents. Poor: strong bases, amines (specific compounds vary) | Injection molding, compression molding | Typical ±0.05–±0.15 mm |
| Silicone (VMQ) | 30–80 A | Food contact, medical devices, extreme temperature seals | -60 to 200 | Good: heat, ozone, weathering. Poor: fuels, many hydrocarbons, some solvents | Compression & transfer molding, extrusion | Typical ±0.05–±0.25 mm |
| PTFE (Polytetrafluoroethylene) | N/A (rigid or filled grades) | Chemical-resistant seals, aggressive media, high-temp static seals | -200 to 260 | Outstanding: virtually all chemicals and solvents; inert | Machining, skiving/flash removal, molding for filled PTFE | Typical ±0.05–±0.30 mm (material-dependent) |
| Perfluoroelastomer (FFKM) | 70–90 A | Top-tier chemical processing, semiconductor, harsh chemical seals | -20 to 260 | Best-in-class chemical resistance including strong acids/bases and solvents | Compression & transfer molding, precision finishing | Typical ±0.05–±0.15 mm |
| Neoprene (CR) | 60–80 A | General sealing, refrigeration systems, weatherproof applications | -40 to 120 | Moderate: refrigerants, some oils; good weather/ozone resistance | Compression & injection molding, extrusion | Typical ±0.05–±0.20 mm |
