Product Description Product DescriptionExceptional Sealing ProwessThe Personalized Precision Fpdm FKM HNBR NBR Silicone Rubber O Ring Seal is engineered with precision to ensure a perfect seal. Its elastic deformation allows these seals to snugly adhere to surfaces, effectively preventing leakage of liquids or gases. In static sealing scenarios, they compress to fill any minor surface imperfections, guaranteeing a superior seal. For dynamic applications, such as reciprocating or rotary movements, their inherent flexibility accommodates slight movements, ensuring an enduring seal. With expertly chosen materials and designs, these O-rings are adept at operating under high pressures (static sealing over 1000Bar), vacuums, or even in corrosive environments. This makes them indispensable in hydraulic systems, chemical equipment, aerospace, and more industries.Versatile Material OptionsCrafted from a variety of rubber materials, our O-rings are designed to excel under diverse conditions. Nitrile Butadiene Rubber (NBR) offers outstanding oil resistance, ideal for fuel and lubricating environments, while Fluororubber (FKM) withstands high temperatures and chemical corrosion, suitable for automotive engines and chemical equipment. Silicone Rubber (VMQ) is excellent in extreme temperatures ranging from -60oC to 230oC. EPDM provides ozone resistance, and PTFE excels against strong acids and alkalis. This material diversity ensures our O-rings meet varied requirements in temperature, pressure, and media, establishing them as a universal sealing solution across numerous industries.Space-Efficient DesignOur O-ring seals boast a compact, space-saving design, ideal for installations in tight or limited spaces. Despite their miniaturized form, they maintain high performance, contributing to lightweight and compact equipment designs. In precision instruments, electronic devices, or micro-hydraulic systems, O-rings deliver reliable sealing where other methods (like gaskets or packing seals) may be too bulky. This advantage makes them the perfect choice for today's highly integrated and space-conscious devices.MaterialNitrile Butadiene Rubber (NBR)Fluororubber (FKM)ColorRed, Black, Blue, etc.CustomizedSizeStandard&CustomizedDensityTypically 0.95-1.25 g/cm3,depending on filler content(common grades: ~1.0-1.1 g/cm3).Usually 1.8-2.0 g/cm3 (high density due to fluorine content).HardnessTypically 40 - 90 Shore A, with common industrial grades at 60 - 80 Shore AUsually 50 - 90 Shore A, with high - performance grades often at 70 - 85 Shore A.Temperature-40°C to +100°C(-40°F to +212°F)-20°C to +200°C(-4°F to +392°F)ToleranceTolerance Class for Cross-Section Diameter (CSD)AS568 Class:- Small sizes: ±0.05-0.13 mm- Medium sizes: ±0.13-0.25 mm- Large sizes: ±0.25-0.41 mmTolerance Class for Inner Diameter (ID)- Small sizes: ±0.13-0.38 mm- Medium sizes: ±0.38-0.76 mm- Large sizes: ±0.76-1.52 mmTolerance Class for Cross-Section Diameter (CSD)AS568 Class:- Small sizes: ±0.05-0.13 mm- Medium sizes: ±0.13-0.25 mm- Large sizes: ±0.25-0.41 mmTolerance Class for Inner Diameter (ID)- Small sizes: ±0.13-0.38 mm- Medium sizes: ±0.38-0.76 mm- Large sizes: ±0.76-1.52 mmAdvantages1.

Regular Inspection: Periodically check the O - ring for signs of wear, such as abrasion on the surface, and aging, which may present as cracking, hardening, or discoloration. This helps to identify potential sealing issues in a timely manner.2. Timely Replacement: Replace O - rings immediately if they are damaged, deformed, or show signs of aging. A defective O - ring can no longer ensure proper sealing performance, which may lead to leaks and affect the normal operation of the equipment.3. Exposure Avoidance: Prevent O - rings from being exposed to harsh environments for extended periods. Extreme temperatures, corrosive substances, and strong oxidizing agents can accelerate the degradation of the O - ring material, reducing its service life.MaterialSilicone Rubber (VMQ)Ethylene Propylene Diene Monomer (EPDM)Polyurethane Rubber (PU)ColorRed, Black, Blue, etc.CustomizedSizeStandard&CustomizedDensityRanges from 0.96-1.25 g/cm3 (lower density than many rubbers; pure silicone: ~0.96-1.05 g/cm3).Generally 0.86-0.95 g/cm3 (one of the lowest densities among common rubbers).Hardness-dependent density: 1.1-1.25 g/cm3 for common grades.HardnessRanges from 20 - 80 Shore A, with common medical/food grades at 40 - 60 Shore A.Generally 40 - 90 Shore A, with standard industrial applications at 50 - 80 Shore A.Hardness spans 60 - 95 Shore A, often used at 70 - 90 Shore A for high - wear resistance.Temperature-60°C to +200°C(-76°F to +392°F)-50°C to +150°C(-58°F to +302°F)-30°C to +80°C(-22°F to +176°F)ToleranceTolerance Class for Cross-Section Diameter (CSD)AS568 Class:- Small sizes: ±0.05-0.13 mm- Medium sizes: ±0.13-0.25 mm- Large sizes: ±0.25-0.41 mmTolerance Class for Inner Diameter (ID)- Small sizes: ±0.13-0.38 mm- Medium sizes: ±0.38-0.76 mm- Large sizes: ±0.76-1.52 mmTolerance Class for Cross-Section Diameter (CSD)AS568 Class:- Small sizes: ±0.05-0.13 mm- Medium sizes: ±0.13-0.25 mm- Large sizes: ±0.25-0.41 mmTolerance Class for Inner Diameter (ID)- Small sizes: ±0.13-0.38 mm- Medium sizes: ±0.38-0.76 mm- Large sizes: ±0.76-1.52 mmTolerance Class for Cross-Section Diameter (CSD)AS568 Class:- Small sizes: ±0.05-0.13 mm- Medium sizes: ±0.13-0.25 mm- Large sizes: ±0.25-0.41 mmTolerance Class for Inner Diameter (ID)- Small sizes: ±0.13-0.38 mm- Medium sizes: ±0.38-0.76 mm- Large sizes: ±0.76-1.52 mmAdvantages1.Extreme temperature tolerance (-60°C to +200°C, short-term up to +260°C).2.Biocompatible and non-toxic, suitable for medical and food applications.3.High flexibility at low temperatures.Good electrical insulation properties.1.Excellent resistance to ozone, UV radiation, and weathering.2.Superior water and steam resistance.3.Low density and good electrical insulation.4.Cost-effective for outdoor and marine applications.1.
