Tetraethyl Lead (TEL) is also known as tetramethyl lead and is commonly used as an antiknock agent in gasoline. It is also used as a stabilizer and corrosion inhibitor in lubricants and as a catalyst in organic chemical reactions.
Rubber materials exposed to TEL can experience swelling, leading to failure of seals, hoses, and other components. The swelling can be severe enough to cause the rubber to crack and tear, or it can cause it to become too soft and lose its sealing properties. In addition, TEL can cause the rubber to become brittle, leading to cracks and other damage caused by pressure or vibration.
