Parco Releases Brochure for Peroxide-Cured, 90-Durometer Nitrile Seals (4623-90)

  • Posted by Parco Inc on February 16, 2007

Ontario, California, February 16, 2007.  Parco, Inc., a leading manufacturer of high performance seals, today released its new peroxide-cured 90-durometer nitrile compound, 4623-90.

Parco developed that compound to be the best performing 90-durometer nitrile on the market.  Its outstanding physical properties also make it an excellent alternative to C67.

Seals made from 4623-90 have a compression set of only 9 percent and an ultimate elongation of 123 percent.  Our 90-durometer nitrile seals can be used in oil field and general purpose applications.

Parco has also released a 2-page brochure describing the benefits of its new compound.  You can view Parco’s new 4623-90 Nitrile Seals brochure in the Literature section of our web site.  If you would like to receive a printed copy, simply contact your Parco customer service representative or e-mail us at
