Its got a fin but its no kipper!

A large finned rubber seal is a type of sealing component that is designed to provide a high level of protection against the entry of water, dust, and other contaminants in a wide range of applications. It is called "finned" because of its distinctive shape, a large flexible fin that allow it to conform to irregular surfaces and provide a tight seal.

The large finned rubber seal is typically made from a durable and flexible rubber material that can withstand wear and tear, as well as exposure to harsh chemicals and extreme temperatures. The fins on the seal allow it to conform to a variety of surfaces, while also providing additional sealing properties.

Large finned rubber seals can be used in a variety of applications, including automotive, industrial, and manufacturing settings. They are often found in doors, windows, and other types of enclosures, where a tight seal is critical to maintaining proper functioning and preventing the entry of contaminants.

Overall, large finned rubber seals play an important role in ensuring the integrity and safety of sealed enclosures. Their flexibility, durability, and sealing properties make them a popular choice for a wide range of applications.
