Continental Contitech 20029115 Heater Hose 50 Ft 5/16 in

Product Description

The CONTINENTAL CONTITECH 20029115 is a 50-foot length of 5/16-inch diameter EPDM automotive heater hose designed for coolant circulation in vehicle heating systems. Constructed with a Versigard EPDM tube and EPDM cover over a spiral reinforcement layer, this hose delivers reliable flexibility and resistance across a wide service temperature range of -40 degrees F to 257 degrees F. The black hose meets SAE J20R3 standards, making it a specification-grade choice for shops performing heater core replacements, coolant system repairs, or custom hose fabrication from bulk stock.

This hose is suited for automotive and light-duty vehicle heater circuit applications where a bulk 50-foot roll allows technicians to cut to length on the bench. Typical installations include heater core inlet and outlet connections, bypass lines, and coolant distribution runs in passenger vehicles and light trucks. The 5/16-inch inside diameter fits standard small-bore heater fittings commonly found in these applications. Auto technicians and fleet maintenance shops will find the bulk format efficient for high-volume service work.

Installation Notes

Installation should be performed by a qualified automotive technician. Drain and recover coolant before removing any hose sections to prevent burns and spills. Cut hose cleanly with a sharp blade and confirm both end fittings are free of corrosion or debris before seating the new hose. Follow vehicle manufacturer torque specifications for hose clamps and verify system pressure holds before returning the vehicle to service.
