This Lochinvar condensate hose is designed to facilitate the drainage of condensation from heating, ventilation, and air conditioning (HVAC) systems. The hose is constructed from Ethylene Propylene Diene Monomer (EPDM), a type of synthetic rubber known for its durability and resistance to heat, weathering, and a variety of chemicals. The hose has an internal diameter of 3/4 inches, which allows for efficient drainage while minimizing the risk of blockages. It is compatible with a range of Lochinvar HVAC systems.
