NB194-90 Extrusion Resistance O-rings
Parker, recognized worldwide as the leader in elastomer development, has formulated a 90 durometer, peroxide-cured nitrile to specifically address the demanding environments of the Energy, Oil and Gas (EOG) industries. Parker NB194-90 provides excellent compression set resistance and extrusion resistance. NB194-90 also offers high temperature resistance as compared with other nitrile elastomers.
NB194-90 Peroxide-Cured Nitrile Combines Excellent Compression Set Capability with Extrusion Resistance
Setting The Standard
Parker, recognized worldwide as the leader in elastomer development, has formulated a 90 durometer, peroxide-cured nitrile to specifically address the demanding environments of the Energy, Oil and Gas (EOG) industries. Parker NB194-90 provides excellent compression set resistance and extrusion resistance. NB194-90 also offers high temperature resistance as compared with other nitrile elastomers.
Applications
In high pressure oilfield applications, extrusion resistance is of the utmost importance. When space or assembly limitations prohibit the use of back-up rings, extrusion resistant orings can provide a good alternative sealing solution. Parker NB194-90 has exceptional extrusion resistance, low compression set and high temperature service capabilities.
Mechanics of Extrusion
Extrusion occurs when a gas or liquid at high pressure forces the seal material into the clearance gap between the mating surfaces. The larger the diametrical clearance, the more likely extrusion will occur. Elevated temperature and chemical compatibility may also influence potential for seal extrusion.
Compression Set Resistance
Compression Set is the amount by which a rubber specimen fails to return to its original shape after release of a compressive load.
