PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
- One of the primary uses for the 1-inch rubber gasket is in the plumbing industry. It's commonly found in compression fittings where it acts as a cushion between two pipe ends or a pipe and a faucet, providing a reliable seal that can withstand varying water pressures without failure. In such environments, the gasket's resistance to corrosion and degradation from water exposure is paramount, making the choice of material critical.
Seals are essential to protecting the bearings of any rotating shaft assembly -They prevent contaminants such as dirt, dust and water, while also preserving the system’s lubricant.

A more comprehensive study of aeration by Dinzburg8 showed that even a minimal level of aeration of an aggressive European SF oil led to protection of a VDF/HFP/TFE compound, but to severe deterioration of an HNBR compound. He notes that aeration increases the severity of aging in oil for silicone and acrylic elastomers, while decreasing the severity for FKM elastomers.
