O Ring Seals are rubber seals or rubber rings used in a variety of industries for a number of sealing
applications. They are great for sealing against liquids, gases, chemicals, and other elements. O
Ring Seals provide excellent chemical resistance and have various shapes and sizes to meet the
needs of any application. They have a low compression set, varying tensile strength, and are
non-flammable. O Ring Seals are ideal for a wide range of industrial applications, including
automotive, aerospace, and marine. They are durable, reliable, and long-lasting, making them an
excellent choice for any sealing application.
Natural Rubber Features:
Natural rubber was originally derived from latex found in the sap of rubber trees. The purified form
of natural rubber can also be produced synthetically. Natural rubber is an ideal polymer for dynamic
or static engineering applications.
Caution: Natural rubber is not recommended for applications where the rubber part will be exposed
to ozone, oils, or solvents.
