EPDM Rubber Hoses marketed by us, are available in a variety of specifications and are designed for certain fluid, temperature, and pressure ranges. A seamless synthetic rubber tube, one or more reinforcing layers of braided or spiraling cotton, wire, or synthetic fiber, and an outer cover are the three layers that make up a rubber hose. EPDM Rubber Hoses are more durable, flexible, and weighty than vinyl hoses. These hoses are more durable in general. They blend the flexibility and durability of rubber with the lightweight of vinyl.
