Description
Product Overview
The HPS HTSC-312-BLK is a premium silicone hose designed for unisex‑adult automotive applications where extreme temperature resistance and pressure stability are essential. Constructed from high‑temperature reinforced silicone, this hose exceeds SAEJ20 specifications, ensuring it can withstand hostile engine environments, rapid temperature fluctuations, and a wide range of pressure demands. The model number HTSC-312-BLK reflects its black coloration and reinforced build, offering a sleek, professional appearance while delivering superior performance. It is not compatible with fuel or oil, but excels when used with water, antifreeze, or coolant, making it an optimal choice for turbocharger cooling lines, intercooler connections, and other high‑heat fluid circuits.
Usage
Designed for heavy‑duty pressure connections, the HTSC-312-BLK excels in high‑performance automotive settings. It is ideal for:
- Turbocharger coolant lines where temperatures can exceed 200°C.
- Intercooler and charge‑air cooling systems that demand flexible yet durable hoses.
- After‑market performance upgrades where reliable heat resistance is critical.
- Racing and track day applications where rapid temperature changes are common.

The hose’s reinforced silicone core prevents expansion under pressure, maintaining consistent flow rates and preventing leaks. Its compatibility with water and antifreeze ensures it can be used in both standard cooling circuits and specialized high‑performance setups. Technicians and DIY enthusiasts alike will appreciate the ease of installation, as the hose’s flexibility allows for tight bends without kinking, while the reinforced layers protect against abrasion from surrounding components.
