Continental Contitech 20029210 Heater Hose 50 Ft 3/4 in

Product Description

The CONTINENTAL CONTITECH 20029210 is a 50-foot automotive heater hose constructed from EPDM (Versigard) compound in both the tube and cover. EPDM delivers excellent resistance to coolant, heat, and ozone degradation, making it a reliable choice for closed-loop heater circuits. The hose measures 3/4 inch in inside diameter and carries a blue cover for easy identification in the engine bay. It meets SAE J20R3 standards and is rated for service from -40 degrees F up to 300 degrees F, covering the full operating range of modern automotive and light-duty cooling systems. Licensed HVAC technicians, automotive mechanics, and fleet service professionals routinely stock bulk hose lengths for cut-to-fit installations.

This hose is suited for heater supply and return lines in passenger vehicles, light trucks, vans, and similar applications where SAE J20R3-compliant coolant hose is specified. The 50-foot bulk length allows a single roll to supply multiple vehicles or service multiple heater core connections on larger cab-over or fleet vehicles. The spiral reinforcement construction helps the hose hold its shape under vacuum and pressure without collapsing during high-flow coolant circulation. It is well matched to shop environments that prefer stocking one continuous length rather than pre-formed hoses.

Compatibility

Designed as a bulk-length, cut-to-fit heater hose for automotive and light-duty vehicle heater circuits requiring a 3/4 inch inside diameter, SAE J20R3-rated EPDM hose.

Installation Notes

Installation is typically performed by automotive or fleet mechanics. Drain or isolate the cooling system and allow the engine to cool completely before removing or installing heater hose. Cut the hose cleanly with a sharp hose cutter or utility knife to ensure a leak-free bead seat against the fitting. Secure each end with an appropriate hose clamp torqued per the vehicle or equipment manufacturer specification.
