FAQ:

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.

Why did my O-ring fail prematurely?

Common causes of O-ring failure include: Chemical Incompatibility: Swelling, softening, or cracking due to fluid exposure. Improper Sizing: Using an incorrect size leads to over-compression or inadequate sealing force. Abrasion: Wear and tear from rough surface finishes or contaminated fluid. Extrusion: The seal is forced into the gap between metal parts under high pressure. Installation Damage: Nicks, cuts, or twists during assembly.

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.

How can I prevent seal damage during installation?

Use Tools: Always use dedicated installation tools (e.g., picks, cones, guides). Lubricate: Always lubricate the seal and the contact surface. Protect Sharp Edges: Cover sharp threads and edges with tape or use an installation sleeve. Check the Groove: Ensure the installation groove is clean, deburred, and undamaged.

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.
