Continental Contitech 20029145 Heater Hose 250 Ft 3/4 Inch

Product Description

The CONTINENTAL CONTITECH 20029145 is a 250-foot bulk roll of 3/4-inch diameter automotive heater hose constructed from EPDM (Versigard) tube and cover material. Designed for coolant transfer in automotive and light-duty heating circuits, this hose handles a continuous temperature range of -40 degrees F to 257 degrees F, making it suitable for year-round service in harsh climate conditions. The spiral reinforcement construction maintains flexibility under vacuum and pressure cycling. It meets SAE J20R3 standards, confirming it for use in original-equipment and service-replacement heater circuits. Auto technicians, fleet maintenance shops, and HVAC installers working on vehicle heating systems are the primary installers of this product.

This hose is intended for automotive and light-duty vehicle heater circuits where coolant is routed between the engine and the cabin heater core. The 250-foot bulk roll format is practical for shops that perform high-volume heater hose replacements or custom-length fabrication. The black EPDM cover resists ozone, heat, and abrasion. SAE J20R3 compliance makes this hose appropriate for use in passenger vehicles and light trucks wherever that specification is called for by OEM service documentation.

Installation Notes

Installation is typically performed by automotive technicians or fleet maintenance professionals. Drain or capture engine coolant before removing existing hose to avoid spills and contact with hot coolant. Cut the bulk hose to the required length using a sharp hose cutter for a clean, square end, and secure with appropriate hose clamps torqued to vehicle manufacturer specifications. Allow the engine to cool completely before beginning work, and follow all shop safety practices for coolant handling and disposal.
