A heat shrink seal is a protective covering made from thermoplastic materials that shrink when heated. It is commonly used to insulate and safeguard electrical connections, providing a moisture-resistant and durable seal. Once applied, the heat causes the material to contract tightly around the object, creating a secure and reliable barrier. Heat shrink seals are widely used in various applications, including electronics, automotive, and packaging industries.
Seals have good memories....... Watch your back!

An inflatable seal is a type of rubber seal that inflates and deflates based on the presence of an inflation source. This allows the seal to accommodate a variable sealing gap. When pressure is applied internally to the seal, it inflates to conform to uneven surfaces and provides a reliable barrier from moisture, damp and other contaminants.
