 Increase Seal Integrity with Custom Rubber O-Rings

Title: Prevent Fluid Leaks with High-Precision Rubber O-Rings

Introduction:

A single failing rubber O-ring can shut down an entire production line. These tiny circular seals are critical for hydraulic and pneumatic systems. When you buy rubber O-rings, you are buying peace of mind. Let’s look at why rubber O-rings are the world's most popular sealing solution.

1. Definition and Geometry

A rubber O-ring is a torus-shaped loop of elastomer. It is designed to be seated in a groove and compressed during assembly to create a leak-proof rubber seal.

2. Why Choose Rubber O-Rings?

  • Versatility: Can seal vacuum or thousands of PSI of pressure.

  • Cost-Effectiveness: High performance at a low unit price.

3. Material Comparison Table

Material Trade Name Best For
FKM Viton High Temp / Chemicals
Buna-N Nitrile Oil / Fuel
VMQ Silicone Food Grade / Medical

4. How to Prevent O-Ring Failure

  • Avoid Over-compression: Aim for 10-30% squeeze.

  • Lubrication: Use compatible grease to prevent tearing during installation.

Conclusion:

The right elastomeric ring makes all the difference. For material compatibility charts, refer to theChemical Resistance Guide.

FAQs:

  • What causes O-ring "nicking"? Poor groove finish or sharp installation tools.

  • How do I measure an O-ring? Inside Diameter (ID) x Cross Section (CS).
