Product Introduction
We supply high-quality 382pcs 30-size & 32-size rubber O-ring repair kits under YOUQI brand, manufactured in Shanghai, China. This is a standard mechanical sealing product compliant with multiple international standards including AS568, BS1516, JISB2401, ISO3601, DIN 3771 and JB/T7757. The O-ring kit includes diversified specifications ranging from 4*1mm to 500*8.6mm, covering both standard and non-standard sizes, equipped with O-rings and X-ring gaskets, which is an essential tool for mechanical maintenance.
The O-ring kit supports multiple premium materials, including NBR, HNBR, NR, FKM, EPDM, PTFE, Viton and Silicone, available in black, white, red, green, brown and other customized colors. The product hardness is stable at 70-75 Shore. Different materials feature distinct temperature resistance ranges: NBR (-30°C ~ +120°C), FKM (-20°C ~ +200°C), PU (-45°C ~ +110°C), PTFE (-55°C ~ +260°C), Silicone (-60°C ~ +230°C), EPDM (-50°C ~ +150°C), HNBR (-30°C ~ +140°C). The long-term operating temperature ranges from -60°C to +220°C depending on different materials.
Featuring excellent ozone resistance, corrosion resistance and reliable electrical insulation, these O-rings are widely applied for static sealing in water, oil, gas, chemical solvent and chemical liquid environments, and also applicable to semiconductor vacuum environments. The maximum pressure is less than 20MPa for static sealing and less than 5MPa for dynamic sealing, varying by material. OEM customization service is fully supported to meet diverse customer needs.
