C0944-70 Datasheet

Parker’s C0944-70 is a 70 Shore A red Neoprene (Chloroprene, CR) compound developed for general-purpose sealing applications that require a balance of oil resistance, environmental durability, and mechanical stability. With a service temperature range of -35°F to 250°F, it performs reliably in contact with paraffin-based mineral oils, silicone oils and greases, water and water-based fluids at lower temperatures, refrigerants, ammonia, and carbon dioxide. Compared to nitrile, this compound offers improved resistance to ozone, weathering, and aging, supporting longer service life in outdoor and industrial environments. Its medium durometer provides a practical combination of flexibility and extrusion resistance for both static and moderate dynamic sealing conditions.

 

C0944-70 meets ASTM D2000 M3BC710 requirements and is commonly used in industrial equipment, refrigeration systems, and general machinery where environmental exposure is a concern. It has limited compatibility with naphthenic mineral oils such as IRM 902 and IRM 903 and with glycol-based brake fluids. This compound is not recommended for aromatic hydrocarbons, chlorinated hydrocarbons, or polar solvents such as ketones, esters, and ethers. Canyon Components offers equivalent chloroprene materials that match or exceed the performance of Parker C0944-70 for general-purpose and environmentally exposed sealing applications.
