Dayco 87969 HVAC Heater Hose - Lower

Heater Hose Overview

Dayco 87969 is a branched HVAC heater hose built for applications that require a small inside diameter hose with multiple branch connections. It uses EPDM construction and a protective sleeve to support heat and abrasion resistance in demanding underhood routing.

Compatible with Ford E-Series applications that use a lower heater hose with auxiliary heater or A/C notes, this hose is specified for direct replacement use in the listed vehicles. The branched layout and SAE J20R3 Class D-1 / SAE J1684 Type EC specifications make it a fitment-focused solution for service work on Ford E-150, Ford E-250, and Ford E-350 Super Duty platforms.

• EPDM rubber construction for heater hose service
• Branched hose design for multi-path coolant routing
• Protective sleeve included for added abrasion protection
• Black finish for a factory-style appearance
• Built to SAE J20R3 Class D-1 and SAE J1684 Type EC standards
