Tip: Rubber O-ring. We get some inquiries from website viewers who are looking for a natural rubber o-ring so we thought we would publish a few words about what a rubber o-ring really is. It is virtually impossible to find an o-ring that is made from natural rubber - the stuff that comes from rubber trees - today. What you will find instead is a product that is made out of a synthetic material, called an elastomer, that looks, feels and behaves like one might think natural rubber would.
O-rings come in a variety of sizes British Standard (BS) which are imperial sizes or metric sizes. Typical dimensions of an O-ring are internal dimension (id), outer dimension (od) and thickness / cross section (cs). Metric O-rings are usually defined by the internal dimension x the cross section.Typical part number for a metric O-ring-ID x CS [material & shore hardness ] 2x1N70 = defines this O-ring as 2mm id with 1mm cross section made from Nitrile rubber which is 70Sh. BS O-rings are defines by a standard reference.he first patent for the O-ring, is dated May 12, 1896 as a Swedish patent. J. O. Lundberg, the inventor of the O-ring, received the patent. The US patent for the O-ring was filed in 1937 by a then 72-year-old Danish-born machinist, Niels Christensen.
