Gates Heater Hose 6 ft (3/4 in ID) Green — EPDM, SAE 20R3 Class D-2 Durable Coolant Line

Gates 28492 Safety Stripe is a six-foot, 3/4-inch inner-diameter heater hose made from durable EPDM, designed for long-lasting coolant service in cars and light trucks.

This green Safety Stripe heater hose from Gates is engineered to resist heat, common engine coolants, and pressure found in automotive heating systems. Built to SAE 20R3 Standard Wall Class D-2, it provides a dependable replacement line for heater cores, hoses to and from the intake, and other low-pressure coolant routing. The hose ships in a reusable, pegboard-ready package so you can keep spare hose on hand for scheduled maintenance or emergency repairs.

What materials make this hose suitable for engine cooling systems?

The Gates 28492 is constructed from EPDM (ethylene propylene diene monomer), a synthetic rubber known for heat and coolant resistance. EPDM resists degradation from most water-based coolants and many non-oil-based additives, helping the hose keep flexibility and strength over time.

• EPDM compound resists heat and coolant chemicals
• Meets SAE 20R3 Standard Wall Class D-2 for construction
• Temperature range: -40°F to +257°F (-40°C to +125°C)

Will this hose handle my vehicle’s operating temperatures and pressures?

Yes — this hose is rated for wide temperature extremes and is intended for the pressures typical of passenger cars and light trucks' heater circuits. It is not designed for heavy-duty or off-road applications that can generate higher pressures or harsher conditions.

• Continuous temperature capability up to +257°F (+125°C)
• Suitable for standard cooling system pressures in cars and light trucks
• Not recommended for heavy-duty trucks, buses, or construction equipment

How should I use and care for the Gates Safety Stripe heater hose?

Cut to length as needed and secure with appropriate clamps at each connection point. Avoid contact with oil or fuel, as this hose is not formulated for hydrocarbon transfer; periodic inspection will catch wear or swelling before failure.

• Cut and install with automotive-grade hose clamps or spring clamps
• Do not use for fuel or oil transfer applications
• Store in original reusable package to protect hose shape and keep inventory

Who this is for: Technicians, DIY mechanics, and fleet operators who maintain passenger cars and light trucks and need a reliable, reusable-length heater hose for coolant lines. Choose the Gates 28492 if you require a durable EPDM hose that meets SAE 20R3 Class D-2 standards, performs across a wide temperature range, and comes in a convenient 6-foot, display-ready package. If you manage heavy-duty vehicles, buses, or off-road equipment, consider Gates Green Stripe or hoses specified for high-pressure, heavy-duty service instead.
