FAQ

1. What is an O-Ring?
An O-Ring is a circular elastomeric seal with a round cross-section, designed to prevent fluid or gas leakage in mechanical systems. It works by compressing between two surfaces, creating a reliable barrier against contaminants and pressure loss.

2. What materials are available for O-Rings?
We provide high-performance materials compliant with international standards:
- **NBR (Nitrile Rubber)**: Oil-resistant, ideal for automotive and industrial applications.
- **FKM/FPM (Fluoroelastomer/FKM®)**: Resists extreme temperatures (-20°C to +200°C) and chemicals.
- **Silicone (VMQ)**: Non-toxic, flexible, and heat-resistant (-60°C to +230°C), perfect for food, medical, and aerospace industries.
- **EPDM**: Excellent for water, steam, and UV/ozone resistance.
- **PTFE**: Chemically inert, suits aggressive media.
*Custom materials (e.g., FDA/USP Class VI, RoHS, REACH) available upon request.*

3. How to choose the right O-Ring size?
We follow **ISO 3601** and **AS568** standards. Provide us with:
- **Inner Diameter (ID)**
- **Cross-Section (CS)**
- **Application details** (pressure, temperature, media).
*Need help? Our engineers offer free technical support.*

4. What causes O-Ring failure?
Common issues include:
- **Improper installation** (twisting, over-stretching).
- **Material incompatibility** (chemical swelling or degradation).
- **Extreme temperatures/pressure** beyond design limits.
- **Aging** due to ozone/UV exposure.

5. How to ensure proper O-Ring installation?
- Clean grooves thoroughly; remove sharp edges.
- Lubricate with compatible grease (e.g., silicone-based).
- Avoid stretching >5% during assembly.
- Use installation tools for precision.
*Download our installation guide [link] or request training.*

6. Do you offer custom O-Rings?
Yes! We specialize in:
- **Non-standard sizes** (micro to large diameters).
- **Special shapes** (X-rings, square rings).
- **Tailored materials** (anti-static, conductive, low-temperature).
- **Color coding** for easy identification.
*Submit your CAD drawing or specifications for a quote within 24 hours.*

7. What certifications do your products have?
We comply with:
- **ISO 9001:2015** (quality management).
- **FDA, USP Class VI** (food/medical).
- **RoHS/REACH** (environmental compliance).
- **ASTM International** standards.

8. What is your MOQ and lead time?
- **MOQ**: Flexible (from prototypes to bulk orders).
- **Standard products**: 5-7 days.
- **Custom orders**: 2-4 weeks (depending on complexity).
*Express shipping and bonded inventory options available.*

9. How to store O-Rings?
- Keep in original packaging, away from direct sunlight.
- Store at 15-25°C; avoid ozone sources (e.g., motors).
- Shelf life: Up to 10 years for most materials.

10. Why choose us as your O-Ring supplier?
- **Global expertise**: Serving 50+ countries in automotive, oil & gas, and pharmaceuticals.
- **Cost-effective**: Competitive pricing with no compromise on quality.
- **Technical partnership**: Free material selection advice and failure analysis.
- **Logistics excellence**: DDP terms, air/sea shipping, and door-to-door delivery.

11. Do you provide samples?
Yes! Request free samples to test performance in your application.

12. What if I need urgent replacement?
Our 24/7 emergency service guarantees fast-track production and global shipping.
