About O-Ring Design

Designing an O-ring seal starts with choosing the right compound as it significantly influences the gland design. The primary consideration is the fluid to be sealed, but the material should also withstand maximum system pressure and maintain its properties across temperature variations. For dynamic use, it should offer toughness and abrasion resistance crucial for reciprocating and rotary seals.

Key specifications include:

• Materials: NBR, EPDM, FKM, SIL, HNBR, etc.
• Hardness: 30~90 Shore A
• Temperature Range: -20℃ to 220℃
• Performance: Excellent sealing, water and oil resistance, anti-aging, and insulation properties
• Applications: Faucets, toilets, fittings, pipes, showers, industry accessories, and auto parts
• Certifications: SGS, RoHS, and FDA
• Customization: Various colors, sizes, and drawings accepted
• Packaging: PP bags and carton boxes
• Delivery: Prompt and efficient

O-rings, typically molded from elastomers, are torus or doughnut-shaped rings used primarily for sealing, but also serve as light-duty mechanical drive belts.
