🏭 Reliable Production Capacity Tengye specializes in rubber sealing products with complete compression molding equipment and independent mold-making workshop. We strictly control all production links. Premium nitrile compounds are selected, no recycled inferior materials. Every batch gets full quality inspection, keeping consistent quality of NBR O-Ring for overseas industrial purchasers.
🧪 Premium Raw Material Control High-quality NBR compound is selected to manufacture our nitrile O-ring. All raw batches pass lab inspection before production. Strict raw material screening lays a solid foundation for excellent oil resistance, abrasion resistance and extended service life of finished NBR O-Ring.
⚙️ Molding & Vulcanization Flow We use compression molding and vulcanization process. ➤ Process steps: Compound mixing → Mold preparation → Molding → Vulcanization → Deburring → Dimensional check QC team monitors every step to guarantee smooth surface, uniform cross-section and consistent hardness of each batch of NBR O-Ring.
🌡️ Performance & Key Specifications NBR O-Ring can run stably within -30℃ ~ +120℃. ✅ Product advantages: • Good resistance to mineral oil, lubricating oil and fuel • High abrasion resistance and mechanical toughness • Low compression set for long-term reliable sealing • Hardness 60–90 Shore A customizable to working condition
📍 Typical Application Scenarios Ideal for hydraulic systems, pneumatic valves, oil pumps, automotive fuel circuits, engineering machinery and lubrication pipelines. Adaptable to indoor machinery rooms and outdoor equipment with oil exposure, pressure and temperature changes. Many system manufacturers choose NBR O-Ring for these demanding working conditions.
