HPS Performance Products SC-400-L4-HOT Silicone Coupler Hose 4" ID x 4" Long Orange

The HPS Performance Products SC-400-L4-HOT is an ultra high-temperature, 4-ply aramid reinforced silicone coupler hose designed for demanding performance and industrial applications. With a 4-inch inner diameter and 4-inch length, this straight silicone coupler is built to handle extreme heat and high-pressure connections in custom turbo systems, intercooler piping, intake builds, radiator cooling systems, and marine or industrial fabrication projects.

Key Features:

• Ultra High-Temp Rated: Maximum temperature rating of 500°F (260°C), making it suitable for high-performance and forced induction applications
• 4-Ply Aramid Reinforced Construction: Four layers of aramid fiber reinforcement provide superior burst strength, pressure resistance, and long-term durability
• Meets and Exceeds SAE J20 Standards: Engineered to exceed industry standards for heavy-duty pressure connections
• UV and Ozone Resistant: Maintains integrity and flexibility even after prolonged exposure to sunlight and environmental elements
• Versatile Application: Ideal for custom turbo or intercooler piping fabrication, DIY intake systems, radiator cooling systems, and marine or industrial use
• Vibrant Orange Finish: High-visibility orange color for a clean, professional engine bay appearance
• Not Compatible with Fuel or Oil: Designed exclusively for air, coolant, and water applications — do not use with petroleum-based fluids

Built from premium high-temperature silicone, this HPS coupler hose delivers consistent performance under pressure and heat where standard rubber hoses fail. The straight coupler design simplifies installation in both custom fabrication and replacement scenarios, making it a go-to choice for performance builders and fabricators.
