When should I use a spring-energized seal instead of a standard elastomeric seal?
Consider a spring-energized seal (e.g., GSF, SPN types) for demanding applications involving: Extreme Temperatures (below -30°C or above +200°C) Aggressive Chemicals that elastomers can't handle Very Low Leakage or "Zero Leakage" requirements Poor Lubricity or dry running conditions The internal spring maintains constant sealing force, compensating for wear and system variables.
How important is surface finish on the metal parts that contact the seal?
Extremely important. A rough surface will abrade and wear out the seal quickly, causing leaks. A finish that is too smooth can prevent a lubricating film from forming. A typical recommended surface finish for dynamic applications is 0.2 to 0.8 μm (8-32 μin) Ra.
How do I choose the right material for my sealing application?
Material selection depends on four key factors: Media: What fluid or gas will the seal contact? (e.g., petroleum oil, water, chemicals, steam) Temperature: What is the minimum and maximum operating temperature? Pressure: What is the system's operating pressure? Are there pressure spikes? Application: Is it a static, dynamic, or rotary seal? Example: NBR (Buna-N) is excellent for standard hydraulic oil, while FKM (Viton®) is needed for high temperatures or aggressive chemicals.
What does "AS568" mean?
AS568 is the Aerospace Standard that defines the dimensions for over 360 standard O-ring sizes. It is the most widely accepted sizing system in North America and globally. An AS568 number (e.g., AS568-214) specifies a precise inside diameter and cross-section.
