Are manufactured from a tube of rubber by inserting a mandrel into the tube and cutting the finished dimensions with a knife while the mandrel is being turned at high speed in a lathe type machine. Lathe cut gaskets offer maximum cost-performance benefits in many applications and is usually the best choice where a static seal is needed. Its square or rectangular cross-section provides a wider sealing surface and superior resistance to compression set than molded O-rings.
Lathe cut gaskets are typically less expensive than molded alternatives and is a great choice for high volume gaskets. Lathe cutting also is good when beveled edge gaskets or tight tolerance gaskets are required. The lathe cutting process is also a good choice when large OD gaskets or small ID gaskets are required. Filter gaskets and food grade gaskets can also be produced using this method.
Gaskets are used in the agriculture, defense, energy & utility, and the government industries. For more information, including technical guides, please look at our seals guides. Updated: 05/20/21
