Parker’s C0873-70 is a 70 Shore A black Neoprene (Chloroprene, CR) compound formulated for sealing applications that require balanced oil resistance, environmental durability, and controlled compression set. With a service temperature range of -35°F to 225°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 provides improved resistance to ozone, weathering, and aging, supporting longer service life in outdoor and refrigeration environments. Its formulation is commonly selected where stable sealing performance and resistance to environmental exposure are critical.
C0873-70 meets ASTM D2000 M2BE710 requirements and is widely used in refrigeration, HVAC, and general industrial sealing applications. It has limited compatibility with naphthenic mineral oils such as IRM 902 and IRM 903 and 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 C0873-70 for refrigerant and environmentally exposed sealing applications.
