O-rings and gaskets are commonly used in various industries, sparking the debate over which type offers superior sealing performance. Let's delve into their similarities and differences.

Similarities between O-rings and gaskets:
Both excel when the sealing contact pressure surpasses the pressure of the sealed medium, ensuring effective sealing.
However, if the sealing contact pressure falls below the medium pressure, there is a risk of displacement, leading to substantial leakage.

Differences between O-rings and gaskets:
Flat gasket sealing involves a combination of the gasket, flange, and bolts, creating a complex system with statically indeterminate properties. The sealing contact pressure is generated through bolt deformation, resulting in a uniform pressure distribution during operation. Yet, fluctuations in medium pressure exceeding the contact pressure can trigger leaks.

Comparison:
Under steady pressure conditions, both O-rings and gaskets can suffice. Nevertheless, in dynamic scenarios where pressure escalates, gaskets may struggle to maintain contact pressure, potentially causing leaks as the medium displaces the sealing gap. In such cases, O-rings outperform gaskets.

In terms of application, gaskets are primarily utilized for static sealing, while O-rings are versatile, catering to both static and dynamic sealing needs in reciprocating linear motion.

Regarding design, traditional gasket sealing methods may lack the necessary rigor, prompting ongoing research into new flange gasket design specifications. Conversely, O-ring design is straightforward and reliable, easily accessible in design manuals, and offers practical and user-friendly solutions.

Ultimately, whether O-rings or gaskets are chosen, the key lies in their suitability and effectiveness in fulfilling their sealing function.
