Neoprene® o-rings is the first synthetic rubber developed commercially, in 1930 by a DuPont chemist, and exhibits generally good ozone, aging and chemical resistance. Chloroprene (CR) is a multi-purposed elastomer which yields a balanced combination of properties. Chloroprene (CR) o-rings are typically seen in the refrigeration sector, as they demonstrate remarkable resistance to chemicals such as ammonia and a variety of coolants. The terms polychloroprene and neoprene are interchangeable, both referring to the same family of synthetic rubbers produced by the polymerization of chloroprene.
Engineered Seal Products has the expertise and inventory for your Neoprene® (CR) o-ring applications. For over 50 years, ESP has been the leading engineering, quality, and supply chain choice for both standard and custom sealing applications. A seal, no matter the application, has to do just that.

O-Ring Temperature Range Chart
Material properties & Temp ranges based on Parker o-Ring Handbook (ORD 5700) recommendations.
Temperature ranges will apply to the majority of media for which the material is potentially recommended. With some media however, the service temperature range may be significantly different. ALWAYS TEST UNDER ACUTAL SERVICE CONDITIONS.
ESP’s shelf life recommendation is based on the ARP 5316 standard and intended to be utilized by those organizations who do not already have specific recommendations for the control of elastomeric seals. It should be noted that the packaging of the elastomeric seals prior to assembly into a product is an integral part of the controlled storage procedure. It provides a positive means of product identity from the time of manufacture, to the time of assembly.
