Daemar Inc. O-Ring, Kalrez Compound 7075 391-K-7075

O-rings made from standard compounds are available from stock in standard AS-568A, metric and JIS sizes. Compound 7075 - Kalrez® Spectrum™ 7075 broadens Kalrez® sealing options with a perfluoroelastomer that has enhanced physical performance properties including very low compression set (12% pellets/15% O-rings per ASTM D 395B) and improved seal force retention. It is a carbon black filled compound utilizing new and proprietary cure chemistry technology with mechanical properties designed for improving sealing performance in both high temperature environments and temperature cycling situations. 7075 joins the family of Kalrez® Spectrum™ products designed for the chemical processing industry. To provide even greater sealing performance in dynamic applications where low friction is required, 7075 O-rings have a glossier finish than other Kalrez® parts. 7075 was specifically developed to be used as an O-ring or custom-sealing component in the chemical and hydrocarbon industries, with an improved thermal resistance that extends maximum service temperature to 327 ºC (620 ºF). Kalrez® Spectrum™ 7075 offers the enhanced elastomeric properties outlined above while providing a chemical resistance better than the industry standard set by Kalrez® 4079.
