When selecting a 1-inch rubber hose, the material composition determines its lifespan and application suitability. EPDM (Ethylene Propylene Diene Monomer) is the industry standard for outdoor use due to its superior resistance to heat, ozone, and weathering. For industrial environments involving oil or fuel splashes, NBR (Nitrile Rubber) is preferred for its oil resistance. Ensure the hose features a high-tensile synthetic textile reinforcement (braided or spiraled) to prevent bursting under pressure.
