Product details
What Is an O Ring?
An O ring is a circular, donut-shaped seal designed to fit into a groove, creating a secure seal when compressed between two mating surfaces. Its simple yet robust geometry makes the O Ring Seal one of the industry’s most widely used sealing solutions.
O Ring Material
Choosing the right o ring material is critical for optimal performance. At hengoseal.com, we specialize in:
- NBR (Buna-N): Excellent oil and fuel resistance.
- VMQ (Silicone): Great for high/low-temperature applications.
- FKM (Viton®): Outstanding chemical and heat resistance.
- EPDM: Superior weathering and ozone resistance.
Beyond basic O ring, we also offer ED seals (FKM/NBR), star-shaped rings (NBR/FKM), PTFE gaskets, and metal-rubber combination washers in both metric and imperial self-centering designs. This breadth of materials ensures we can match the seal to your exact operating conditions.
What Are O Rings Used For?
O rings or o-ring seals are commonly deployed in:
- Hydraulic systems to maintain fluid pressure.
- Pneumatic cylinders to prevent air leakage.
- General industrial machinery for protection against contamination.
- Automotive assemblies (e.g., engines, gearboxes) to ensure oil-tight performance.
Their simplicity, cost-effectiveness, and dependable sealing capabilities make O rings a go-to choice across diverse sectors.
