1981 Peterbilt 348 Upper Radiator Hoses

Heavy-duty flexible hose designed to replace straight or curved coolant hoses. The benefit is maximum coverage with minimum inventory. Hose inside diameter remains constant from end to end. No convolutions inside hose so tube is smooth, allowing free coolant flow. Approved for marine applications.

Product Features:

• Designed to resist electrochemical degradation, which is the leading cause of hose failure
• The steel wire spiral allows them to take on multiple shapes without bending or crushing
• EPDM tube and neoprene cover for longer life
• Polyester fabric-ply reinforcement vulcanizes into shape without unnecessary strain on connections
• Heat, oil, and ozone resistant
• Meets SAE 20R5 Type EC Class D-2 specifications
• Temperature range: -40 Deg. F to +257 Deg. F (-40 Deg. C to +125 Deg. C)
• Caution: Do not use for fuel or oil transportation applications.
• Caution: Do not use for fuel or oil transfer applications.

The Dayco flex radiator hose replaces straight or molded radiator hoses on a wide range of engine applications. Precision molded in standard lengths, it features a knitted reinforcement and synthetic EPDM construction. This hose is designed to prevent splitting, ballooning and elongation as well as resist ozone and other detrimental environmental elements, coolants and temperature variations of -40 Deg. F (-40 Deg. C) to +257 Deg. F (+125 Deg. C). With corrugations that provide excellent hose flexibility without flattening or collapsing, the Dayco flex radiator hose also features a helical steel coil spring for increased flexibility.

Product Features:

• Designed to meet OE specifications
• Not suitable for oil or heat transfer
• Meets SAE J20R4, Class D-2 requirements for improved service hoses
