Question you may concern
Products
What is the difference between a static seal and a dynamic seal?
A Static Seal is used between two surfaces that do not move relative to each other (e.g., pipe flanges, end caps). O-rings and gaskets are common static seals. A Dynamic Seal is used between surfaces that do move (e.g., piston and cylinder, rotating shaft). Rod seals, piston seals, and rotary shaft seals are designed for this purpose.
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.
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.
