S0469-40 Datasheet

Parker S0469-40 is a 40 Shore A rust-colored silicone (VMQ) compound engineered for O-rings and gaskets requiring excellent low-temperature flexibility and stable performance in regulated environments. With a service temperature range of -75°F to 400°F, this material performs reliably in dry heat, moderate water exposure, and applications demanding strong resistance to ozone, aging, and weathering. S0469-40 meets AMS 3301, USP Class VI, and A-A-59588 Class 2a and 2b Grade 40 requirements, making it suitable for aerospace, medical, and industrial sealing applications where compliance and material consistency are critical. It is compatible with fire-resistant hydraulic fluids (HFD-R and HFD-S) and limited petroleum oil exposure, but is not recommended for ketones, acids, silicone oils, or automotive and aircraft brake fluids. Canyon Components offers equivalent silicone materials that match or exceed the performance of Parker S0469-40 for compliant low-temperature O-ring and gasket applications.
