This rubber is made with one or four thicknesses of polyester fabric inserted in a premium quality neoprene.The 3R818 combines the oil and ozone resistance to resistance of the synthetic fabric. It offers exceptional tensile strength.
It is designed for the fabrication, amoung other things, of gaskets on control valves and regulators. It is also commonly used as cold barriers.
