The process of manufacturing seal involves a lot of machining and a specific size seal material. It is referred to as an engineered product and designed under special conditions. Seals are also known for showing characteristics that gaskets are failing to offer. This is the reason why a seal can provide better functionalities when compared it with gasket products. On the other hand, a seal is a dynamic piece that is used to avoid leakage between two parts that show sliding or relative motion.
In case the gasket breaks down, you need to replace the existing gasket with the new one. However, when the seal breaks down , you need to replace both seals and the bearing with the new ones. This is an application where a gasket can be quite handy when compared to a seal. Both gasket and seal are used to avoid the movement of fluid from one direction to another because of the compressive forces. In addition to gaskets, there are rotary seals, O-ring seals , liquid sealants, mechanical seals, shaft seals, valve stem seals, and packings, just to name a few.
Generally, seals require more machining for the sealing surfaces, and a controlled size or quantity of seal material to make it up. These are a dynamic joint and not something that a flat flange gasket is able to seal. Gaskets generally function with two flat flanges and the gasket material and construction can sometimes be chosen later in the design stages. Various material constructions are available and must be selected to correlate with the available flanges and parameters. This has been a very general explanation of this topic, but hopefully it has provided some insight into a basic definition of sealing mechanisms.
Back to the trivia question…we admit, it was sort of a trick question. Now it is time to stump your friends. Just make sure they at least know what a gasket is before you pose the question!

How often should a gasket be changed? Every time any equipment is taken apart and then reassembled, a new gasket should be used. What industries use gaskets? What is a Seal? What are seals used for? How to install a seal? When should a seal be replaced? When a seal breaks down, the entire bearing must be replaced rather than just the seal. Seals are a broader category that includes o-rings , valve stem seals, rotary seals, and mechanical seals.
Unlike gaskets, which are typically used for static applications, seals are found in more active environments in motors, engines, pumps, and rotary shafts. Seals tend to be flat and round, with a tilted inner ring of rubber surrounded by a metal outer ring. Seals are typically used to prevent leaks between two moving parts, and to prevent the intrusion of particles and contaminants into the system.
The process for replacing a broken or damaged seal can be very involved.
