Outus 3/4" 50ft EPDM heater hose reel — 3/4in ID coolant hose, 70 PSI working, UV/ozone resistant

Outus 3/4" 50ft EPDM heater hose is a durable coolant-only hose reel engineered to carry water, steam, and antifreeze between radiator and heater connections while resisting temperature extremes and ozone.

This 50-foot reel from Outus supplies a continuous 3/4" (19 mm ID) heater hose with a 26 mm outside diameter, printed size markings, and EPDM rubber construction rated for wide temperature ranges. It’s designed for coolant circuits in cars, trucks, RVs and many industrial heating applications where water, coolant, or steam transfer is required but petroleum fluids are not suitable.

How does this hose handle extreme temperatures and outdoor exposure?

The hose is molded from EPDM rubber, a material chosen for its resistance to both high and low temperatures and to weathering. It tolerates temperatures from -30 °C to 120 °C (-22 °F to 248 °F) and resists ozone and UV, which helps prevent cracking and premature aging when used in exposed engine bays or outdoor equipment.

• EPDM compound resists heat, cold, ozone, and ultraviolet light
• Operates across -30 °C to 120 °C temperature range
• Printed size markers on hose for easy identification

What pressure can I expect from this coolant hose?

Outus supplies this heater hose rated for typical coolant system demands: 70 PSI working pressure with a significantly higher burst rating to provide an added safety margin. These ratings make it suitable for most radiator and heater core connections in passenger vehicles and light industrial equipment.

• 70 PSI working pressure for continuous system use
• 170 PSI burst pressure for safety under spikes
• Consistent performance for engine heating and cooling lines

Will this hose fit my vehicle or project, and what sizes are important?

This reel supplies 50 feet of tubing with a 3/4" (19 mm) internal diameter and a 26 mm outside diameter, the common size for many heater lines. Because the hose is delivered on a reel, you can cut custom lengths for repairs or fabrication—each section is marked for quick sizing verification during installation.

• Internal diameter: 3/4" (19 mm)
• Outside diameter: approximately 26 mm
• Delivered as a 50 ft continuous reel, cut-to-length convenience

What should I avoid using this hose for?

Outus designed this hose specifically for water-based fluids: coolant, water, and steam. It is not formulated for petroleum-based liquids like gasoline, oil, or power steering fluid, so do not use it in fuel or oil systems where compatibility and safety may be compromised.

• Suitable: coolant, water, steam, heater circuit applications
• Not suitable: fuel, oil, hydraulic fluid, or power steering fluid
• Always verify chemical compatibility before installation

Who is this for? This Outus 3/4" EPDM heater hose reel is ideal for DIY mechanics, professional technicians, and maintenance teams who need a reliable coolant-line solution in automotive, RV, or light industrial settings. If you need a weather-resistant, cut-to-length heater or radiator hose for water or antifreeze service—and require clear sizing markings and a long continuous length—this hose reel is built to make installations and replacements faster and longer lasting.
