- Chemical Resistant: Withstands acids, alkalis, and alcohols
- Superior Flexibility: Suitable for high-pressure sealing applications
- Food Grade Safe: FDA-grade available for food and pharmaceutical use
Common Applications
- Machinery in food and pharmaceutical industries
- Cold rooms, industrial ovens
- Sealing systems in medical devices and laboratory equipment
O-Ring Material Comparison
| Material | Temp Range (°C) | Chemical Resistance | Applications | Advantages | Limitations |
|---|
| Silicone | -60 to +230 | Excellent | Food, Pharma, Cold Storage | High heat, hygienic, safe | Not oil resistant |
| NBR | -30 to +100 | Great with oils | Engines, hydraulic pumps | Cost-effective | Low heat tolerance |
| EPDM | -50 to +150 | Water, acid, UV resistant | Water systems, outdoor use | Great ozone resistance | Not oil resistant |
| Viton | -20 to +250 | Excellent | Chemical, oil industries | Handles harsh chemicals & heat | Expensive |
Frequently Asked Questions about O-Ring Silicone
- Can I use O-Ring Silicone with oil?
Not recommended. Use NBR or Viton instead. - What is the max heat resistance?
Up to +230°C, or +300°C for some special grades - Is it food-grade safe?
Yes, FDA-grade available for food and pharmaceutical uses - How do I choose the correct size?
Refer to AS568 / Metric chart --> Download O-Ring Size Chart or send us a sample - How does it compare to NBR, EPDM, Viton?
Silicone = heat & hygiene; NBR = oil; EPDM = water/UV; Viton = harsh chemicals
