Continental Contitech 20029143 Heater Hose 50ft 3/4in Epdm

Product Description

The CONTINENTAL CONTITECH 20029143 is a 50-foot automotive heater hose constructed from EPDM (Versigard) rubber with a spiral-reinforced construction. Designed for coolant transfer in automotive and light-duty heating circuits, this hose handles a temperature range of -40 degrees F to 257 degrees F, making it suitable for year-round operation in demanding underhood environments. The 3/4-inch inside diameter fits standard heater circuit connections. At 11.98 pounds for the full 50-foot roll, installers can cut to length on the bench for multiple vehicle applications or fleet work. This hose meets SAE J20R3 standards, confirming it is rated for coolant service at elevated temperatures.

This hose is used in automotive and light commercial vehicle heater circuits, connecting the engine coolant system to the cabin heater core and back. A single 50-foot roll is practical for fleet shops, dealership service bays, and independent repair facilities that prefer to stock bulk hose and cut to fit rather than carry multiple precut lengths. The black EPDM cover resists ozone, heat, and engine fluids common in underhood service environments. Both the hose tube and cover are EPDM construction, ensuring consistent performance across the full temperature operating range.

Key Features

• 50-foot bulk roll — cut to length for multiple jobs
• 3/4-inch inside diameter fits standard heater circuit fittings
• EPDM tube and cover (Versigard) for ozone and heat resistance
• Spiral reinforcement provides structural integrity under pressure and thermal cycling
• Temperature rated from -40 degrees F to 257 degrees F
• Meets SAE J20R3 standard for automotive coolant hose

Compatibility

Designed as a bulk OEM-style replacement heater hose for automotive and light commercial vehicle heater circuits requiring a 3/4-inch inside diameter EPDM hose rated to SAE J20R3.

Installation Notes

Installation is performed by automotive and light-duty service technicians. Drain or isolate the coolant system before cutting or removing any heater hose to prevent burns from pressurized hot coolant. Use a sharp utility knife or hose cutter to produce clean square ends for proper clamp seating. Inspect hose fittings and barbs for corrosion or damage before installing new hose, and torque hose clamps per the clamp manufacturer specification rather than by feel.
