HPS Performance 57-1581H-BLK High Temp Reinforced Silicone Heater Coolant Hose Kit - 3-Ply Black

The HPS Performance 57-1581H-BLK is a race-proven, high-temperature 3-ply reinforced silicone heater coolant hose kit engineered to replace factory OEM rubber heater hoses. Constructed from premium-grade silicone reinforced with high-quality polyester, this kit is built to outlast and outperform stock rubber hoses in both daily driving and demanding performance applications.

Standard OEM rubber heater coolant hoses are susceptible to heat soak, causing them to become brittle, crack, and fail under the high-pressure conditions of heavy towing or off-road use. The HPS silicone heater hose kit eliminates these weak points with multi-layer reinforced construction, delivering significantly higher burst pressure resistance and a longer service life than factory components.

Key Features:

• High-temperature 3-ply reinforced silicone construction — rated up to 350°F (177°C)
• Meets or exceeds OE specifications for fit, form, and function
• Pre-formed with correct bends and curves for a direct OEM replacement — no cutting or trimming required
• Includes 100% stainless steel industrial-grade embossed hose clamps that will not cut through silicone hoses
• Race-proven design suitable for competition and everyday driving
• Prevents and corrects coolant leaks and engine overheating caused by cracked, collapsed, or damaged OEM hoses
• Color: Black

Important Note: Silicone hoses have a water permeation rate 10 to 15 times greater than standard EPDM rubber hose. Regular coolant level checks are strongly recommended when silicone coolant hoses are used in daily-driven vehicles.
