WeatherFlex EPDM Suction Hose Type 9904 WeatherFlex EPDM Suction Hose is the original flexible all-weather suction hose designed for outdoor pumping and liquid waste. This hose is a durable all-season option for pump rental, agricultural, and septic hauling applications. A smooth EPDM rubber tube offers flexibility and resistance to light chemicals. The corrugated polyethylene spiral helix provides excellent drag resistance and durability, and will not mark or damage concrete walkways. This hose is stocked in Green or Gray Outer Helix in a variety of sizes. Not recommended for high heat applications where the reinforcement could become soft.

WeatherFlex EPDM has been time tested in the industry for more than 30 years. Other brands have EPDM rubber only between the helix, where WeatherFlex hose has a complete rubber lining for a smooth uniform EPDM rubber interior. This improves durability for a long lasting suction hose assembly.

A wire reinforced option (Type 9924) with black helix is available in 4 inch through 8 inch diameters, suitable for hydro excavation and higher temperature applications.
