Question you may concern

What is the difference between NBR and FKM materials?
NBR (Nitrile/Buna-N): A general-purpose, cost-effective material with excellent resistance to petroleum-based oils and fuels. It has a standard temperature range of -30°C to +100°C (-22°F to +212°F). FKM (Fluoroelastomer/Viton®): A premium material with excellent resistance to high temperatures (up to 200°C+), chemicals, and oils. It is used in more severe environments but is more expensive than NBR.
What is the purpose of the metal spring in a rotary shaft seal?
The garter spring in a shaft seal (e.g., FSKR, SPGO types) provides a constant radial force on the sealing lip. This ensures consistent contact with the rotating shaft, compensating for minor wear, eccentricity, and vibration to prevent lubricant leakage.
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 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.
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.
