O-Ring Material Guide

Choosing the right material is just as important as choosing the right size.

NBR
A versatile and cost-effective material commonly used for general sealing applications. Often a good choice for standard oil-resistant use.

FKM
A higher-performance material known for stronger resistance in more demanding environments, including higher temperatures and more aggressive media.

EPDM
A popular option for water, weather, and outdoor-related applications. Often chosen where general weather resistance is important.

Silicone
A flexible material often used where temperature range and flexibility are important. Common in many general-purpose sealing uses.

Which material should I choose?
The best choice depends on your actual operating conditions, including:
• Temperature
• Media or chemicals involved
• Outdoor exposure
• Pressure and movement
• Industry or application requirements
