O-Ring Viton: China Manufacturer for Industrial Seals

I supply O-Ring Viton seals that keep your machines leak-free under pressure. As a China Manufacturer, I understand the needs of industrial buyers. O-Ring Viton offers excellent chemical resistance, oil resistance, and long service life across temperatures from -20°C to +250°C depending on grade. For your applications in hydraulics, automotive, and chemical processing, these seals resist ethanol, solvents, fuels, and many aggressive media. I provide standard sizes in metric and inches and can custom-molded or machine to your drawings. My quality control is ISO 9001 certified, with strict QC tests, including dimensional inspection and hardness checks. We offer competitive pricing, small MOQ for samples, and scalable production for mass orders with short lead times. If you’re chasing reliability and quick turnaround in China or abroad, I’ll work with you on material spec, durometer, and packing to fit your procurement cycle. Contact me to discuss your exact O-Ring Viton grade, size, and quantity.

Size (ID × CS, mm) Hardness (Shore A) Temperature Range (°C) Tensile Strength (MPa) Elongation at Break (%) Compression Set (% @70°C, 24h) Recommended Applications / Chemical Notes
3.00 × 1.50 70A -20 to 200 (continuous); up to 230 intermittent 12 140 25 Precision instrumentation, pneumatic seals. Excellent with oils, fuels; poor with ketones/esters at elevated temperatures.
10.00 × 2.00 75A -20 to 200 (continuous); up to 230 intermittent 14 130 22 Hydraulic couplings, automotive fuel interfaces. Very good resistance to hydrocarbon-based fluids; avoid strong acids at high temp.
20.00 × 2.50 75A -20 to 200 (continuous); up to 230 intermittent 15 140 20 Automotive fuel systems, oil seals. Compatible with most fuels, oils, aromatics; poor with amines and hot steam.
50.00 × 3.00 90A -10 to 200 (continuous); up to 230 intermittent 16 110 18 Heavy-duty hydraulic seals and static gaskets. High hardness for mechanical durability; strong resistance to oils and many chemicals.
100.00 × 3.00 60A -25 to 200 (continuous); up to 230 intermittent 11 160 28 Static flange seals, chemical tank lids. Lower hardness improves static sealing; suitable for many acids and oils but avoid prolonged hot water exposure.
200.00 × 4.00 70A -20 to 200 (continuous); up to 230 intermittent 13 150 24 Large-diameter process equipment seals. Well-suited for petrochemical media; assess compatibility for aggressive solvents (ketones/esters).
Notes: Typical material properties for fluorocarbon elastomers (Viton/FKM) are shown. Common standards referenced: ASTM D2000 (classification), ASTM D1418 (nomenclature), ISO 3601 (O‑ring dimensions). Actual performance varies with compound formulation and service conditions—validate in application. Shelf life (sealed, dark, 25°C): typical up to 10 years.

New Data Dimension: Elastomer Type vs Durability Score at Elevated Temperature

Explanation: This chart presents a small benchmarking of durability scores for six elastomer material types (Type A through Type F) exposed to elevated-temperature aging in a controlled process. The data dimension used here is material type, a neutral, product-agnostic variable that allows managers and engineers to compare performance without referencing specific suppliers. Each bar reflects a composite durability score on a 0-100 scale, derived from accelerated aging criteria such as thermal oxidation resistance, compression set after cycling, and resistance to softening at a representative operating temperature around 120-150°C. The scores are intentionally synthetic to illustrate how the chart conveys relative ranking: Type C shows the strongest performance, while Type D trails the field, with Type A, B, E, and F distributed in between. The chart uses a 0-100 axis with gridlines every 20 points to promote quick interpretation of magnitude and changes across categories. Color variation across bars provides an at-a-glance sense of relative strength, with warmer tones generally aligned with higher durability in this fictional dataset, though color should not be used as the sole determinant of material choice in practice. The primary takeaway is not the absolute numbers but the order of performance and the spread between top and bottom performers. This kind of visualization supports decision-making in the early stages of seal design by highlighting which material families may warrant further, more granular testing under elevated temperature conditions. Keep in mind that real-world results depend on multiple interacting factors, including humidity, pressure, chemical exposure, and compression history. A larger, more rigorous test matrix would be required to derive definitive recommendations. This simplified depiction should be read as a conceptual demonstration of how a neutral material-type dimension can illuminate comparative durability in a temperature-stressed sealing system.
