Q&A

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.

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.

Can I reuse a seal?

We strongly recommend never reusing seals. Once compressed and used, a seal takes a "set" and its elastic properties are degraded. Reusing it almost always results in a leak. Always install a new seal during any maintenance or repair.
