Black High Temperature GENUINE Viton® (DuPont B) Rubber 70° shore

SM281 Black High Temperature Genuine Viton® (DuPont B) Rubber 70° shore is a Genuine Viton® GRADE B. Grade B offers better chemical resistance than Viton® A with superior flexibility in higher heat applications. Our Viton B is an excellent choice for power stations where Sulfur Dioxide is present along with many other applications where a superior product, to the already impressive Viton® A, may be required due to higher temperatures and or additional resistance to chemicals or oils.
