Which type of seals tend to stretch more than the others?

Silicone seals are known for their unique properties, including excellent elasticity, flexibility, and stretchability. Compared to other materials, silicone can stretch significantly without losing its original form, making it ideal for creating a watertight seal in varying conditions. This characteristic allows silicone seals to conform better to the surface they are sealing against, reducing the chances of any leaks that might occur with less elastic materials. Moreover, silicone maintains its flexibility across a wide range of temperatures, which enhances its performance in dynamic environments such as those encountered while diving.

In contrast, while neoprene and latex materials are also used for seals, they typically have more limited stretch capabilities compared to silicone. Neoprene tends to be more rigid, offering good insulation but less stretch, while latex can stretch significantly but is generally not as durable or as resistant to environmental factors as silicone. Plastic seals, on the other hand, are usually rigid and typically do not offer any stretch, which is not suitable for applications requiring flexibility. Thus, silicone's superior stretching ability clearly makes it the best choice among the options presented.
