Description
Product Overview
The HPS HTSC-275 silicone hose is engineered for unisex‑adult automotive applications, specifically targeting turbocharger and supercharger cooling systems. Constructed from high‑temperature reinforced silicone, the hose exceeds SAE J20 specifications, ensuring resistance to heat, pressure, and harsh chemicals. Its black exterior offers UV protection and a professional appearance. The model number HTSC-275‑BLK reflects the 2.75‑inch nominal diameter and black color, making identification simple during installation. Designed for water or antifreeze (coolant) transport, the hose delivers consistent flow while withstanding temperatures that would degrade conventional rubber hoses.
Usage
Ideal for performance enthusiasts, race teams, and daily drivers who demand reliable cooling under high boost conditions, this hose excels in turbocharger coolant circuits, intercooler feed lines, and supercharger water jackets. It thrives in environments where temperatures fluctuate between sub‑zero winter climates and scorching summer engine bays. Because the silicone material is inert to coolant and antifreeze, it prevents corrosion and swelling, extending service life. Installers should avoid contact with gasoline or engine oil, as silicone is not compatible with those fluids.

Why Choose Us
HPS Silicone Hoses has a reputation for precision manufacturing and rigorous quality control. Each hose undergoes a multi‑stage testing process, including tensile strength, burst pressure, and temperature cycling, to guarantee performance that meets or exceeds industry standards. The reinforced silicone core provides superior flexibility without sacrificing durability, allowing easy routing around tight engine bays. Our commitment to SAE J20 compliance means you receive a product that has been validated for high‑pressure, high‑temperature applications, giving you confidence in demanding builds.

FAQ
Can this hose be used for fuel lines?
No. The silicone material is not compatible with gasoline or diesel. Use a hose specifically rated for fuel.
What temperature range does the hose support?
The reinforced silicone can handle continuous temperatures up to 260 °C (500 °F) and short‑term spikes beyond that, making it suitable for high‑performance turbo applications.
Is the hose compatible with both water and coolant?
Yes, it is safe for water, antifreeze, and mixed coolant solutions. It resists corrosion and swelling when exposed to these fluids.
How does the hose meet SAE J20 standards?
Each hose is tested for burst pressure, tensile strength, and temperature cycling to ensure it meets the SAE J20 specifications for high‑pressure, high‑temperature automotive hoses.
What is the recommended installation method?
Secure the hose with appropriate clamps rated for the operating pressure. Ensure clamps are tightened evenly to avoid pinching the silicone, which could restrict flow.
