Waterproof rubber gaskets are indispensable solutions for systems requiring absolute sealing, effectively preventing water leaks. Made from high-quality rubber, these gaskets are notable for their superior durability, flexible elasticity, and heat resistance, making them ideal for both industrial and household applications. In this article, we’ll share everything you need to know about waterproof rubber gaskets to help you choose the right product.
Waterproof Rubber Gaskets: Key Information
O-Ring Rubber Gaskets are a popular sealing solution due to their cost-effectiveness, flexibility, and suitability for both static and dynamic applications. Important points to know about standard O-ring sizes:
-
Size calculation formula: OD = ID + 2 × CS (Outer Diameter = Inner Diameter + 2 × Cross-Section Diameter).
-
International standards: O-ring size and quality vary by country and region.
-
Tolerance limits: Exceeding tolerance can lead to leaks.
-
Elastic material: O-rings are made from materials that return to their original shape after deformation.
Understanding these features helps in selecting and using O-rings effectively.
