C1124-70 Datasheet

Parker’s C1124-70 is a 70 Shore A black Neoprene (Chloroprene, CR) compound engineered for low-temperature sealing applications requiring flexibility, oil resistance, and strong environmental durability. With a service temperature range of -60°F to 250°F, it maintains elasticity in cold conditions while performing reliably 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, making it well suited for outdoor, refrigeration, and aerospace-related environments. Its TR-10 low-temperature performance supports dependable sealing where temperature cycling is a concern.

 

C1124-70 meets ASTM D2000 M3BC707 requirements and carries AMS 3209 approval, confirming its suitability for aerospace, military, and industrial sealing applications. 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 C1124-70 for low-temperature and environmentally exposed sealing applications.
