Long-Term Testing of Base Resistant Elastomers (BRE) Suitable for Power Cylinder Systems

Longer warranties, improved performance and higher operating efficiency demanded by end-users are placing more rigorous service requirements on all engine components. Seals are particularly vulnerable due to their organic nature. This paper reviews a series of fluoroelastomers to determine their long-term serviceability when in contact with conventional high-temperature engine lubricants and coolants. A typical application might be seals used for engine cylinder sleeves.
