Rubber is one of the oldest and most commonly used industrial hose materials. Plastic, on the other hand, offers a number of the benefits of rubber, including its flexibility, but with added chemical and heat resistance. Whichever type of product you require, SEMCOR can help. As one of the most comprehensive industrial hose suppliers in the Midwest, we carry a wide range of rubber and plastic hose products by Boston, Home Rubber Company, Kuriyama and Resistoflex.
