The basicThe basic requirement is that the rubber seal tightness, safety and reliability, long life, and strive to make the seal structure is compact, simple system, easy maintenance of manufacturing and low cost. Most rubber seals are wearing parts, should ensure interchangeability, standardization, serialization. Wherein the gasket most commonly used, the most widely used.

Rubber seals sealing material requirements generally:

1) rubber seal dense material, and not leaking medium;

2) rubber seals have suitable mechanical strength and hardness;

3) rubber seals compressibility and resilience, and permanent deformation; 4) Material under high temperature does not soften the rubber seals, does not decompose at low temperatures without hardening, embrittlement; 5) good corrosion resistance in acid, alkali, oil medium, long-term work, its small size and hardness changes, and not adhering to the metal surface; 6) low coefficient of friction, good wear resistance; 7) having a sealing surface binding softness; 8) resistant to aging, durable; convenient material manufacturing 9) rubber seals, cheap, easily drawn.
