O-Ring 809.30mm ID x 5.70mm CS Neoprene (CR) 70 ShA black -40°C to +100°C

Neoprene (CR) is a versatile synthetic elastomer known for its excellent balance of chemical resistance, flexibility, and mechanical properties. It performs well in a variety of challenging environments, offering superior resistance to oils, fuels, weathering, ozone, and aging. Resistant to refrigerants such as ammonia and Freon® (R12, R13, R21, R22, R113, R114, R115, R134A), silicone oils, water, ozone, vegetable oils, alcohols, and low-pressure oxygen.
