NAPTHA Resistant O-Rings and Seals

Naphtha, also known as petroleum hydrocarbon or aliphatic hydrocarbon, is a highly volatile and flammable liquid derived from coal tar or petroleum. It is commonly used as a solvent in a variety of industries, such as paint and varnish manufacturing, and as a fuel for stoves, lanterns, and campfires.

When rubber is exposed to naphtha, it can cause various types of failure. The most common type of failure is swelling, which occurs when the naphtha seeps into the rubber, causing it to expand and weaken. Other types of failure include cracking, hardening, and discoloration of the rubber. In extreme cases, prolonged exposure to naphtha can cause the rubber to become brittle and break down completely.
