Gates Heater Hose 3/4 in x 6 ft Green Safety Stripe — EPDM coolant hose, 50 psi, SAE 20R3

Gates 28492 Safety Stripe heater hose is a 6-foot, 3/4" inner-diameter EPDM coolant hose engineered for cars and light trucks that resists heat, common coolants and high cooling-system pressures.

This heater hose is molded from durable EPDM compound and finished in green with a safety stripe for easy identification. It’s made to meet SAE 20R3 Standard Wall Class D-2 requirements and is specified for normal passenger vehicles and light-duty trucks. The hose resists high temperatures and most non-oil-based coolant additives while delivering a long service life in standard engine cooling systems. Note: it is not intended for fuel or oil transfer or heavy-duty off-road equipment.

How does this heater hose stand up to engine heat and pressure?

The EPDM construction provides strong thermal stability across a broad temperature range and resists the swelling and breakdown that shorten hose life. It’s rated for continuous use from -40°F to +257°F (-40°C to +125°C) and handles typical passenger-vehicle cooling pressures up to 50 psi.

• EPDM material resists heat aging and degradation
• Temperature range suited for cold starts and high-load operation
• 50 psi working pressure for standard cooling systems
• Meets SAE 20R3 Standard Wall Class D-2

Will this hose work with my coolant and additives?

Gates Safety Stripe hose tolerates most coolants and non-oil-based coolant additives commonly used in passenger vehicles and light trucks. Avoid using it with fuel, oil, or oil-based additives because EPDM is not formulated for hydrocarbon exposure.

• Compatible with ethylene- and propylene-glycol based coolants
• Works with most aftermarket non-oil coolant conditioners
• Not suitable for fuel, oil, or oil-mixed chemicals
• Recommended for standard passenger and light-truck systems only

How easy is it to install and maintain this 6-foot hose?

The hose comes in a reusable, recyclable package designed for pegboard display, making storage and selection easy. Its standard 3/4" inner diameter fits many heater core and inlet/outlet ports; cut to length and secure with proper clamps for a reliable seal.

• Convenient 6-foot length for trimming to fit various layouts
• Reusable, recyclable retail packaging for storage
• Trim-to-fit installation with standard hose clamps
• Visual green color and safety stripe simplify identification

What limitations or precautions should I know?

This product is designed for cars and light trucks only and is not recommended for heavy-duty trucks, buses, or construction equipment that demand specialty green-stripe heavy-duty hose. Do not use it for fuel, oil transfer, or in systems exposed to petroleum-based fluids.

• Not rated for heavy-duty or off-road heavy-equipment applications
• Not for fuel or oil transfer—use specified hoses for hydrocarbons
• Observe manufacturer torque and clamp guidelines during installation
• Replace if cracked, softened, or visibly degraded

Who is this for: The Gates 28492 Safety Stripe 3/4" x 6 ft. heater hose suits DIY mechanics, independent shops and fleet maintenance teams servicing passenger cars and light trucks. Choose this hose when you need a cost-effective, heat-resistant EPDM replacement for heater cores, inlet/outlet lines, and short coolant runs where compatibility with common coolants and straightforward installation are priorities.
