Description
Product Overview
The HPS CAC-300-350-HOT silicone turbo hose is engineered for demanding charge‑air applications where reliability, temperature resistance, and flexibility are paramount. Constructed from a high‑temperature 4‑ply silicone matrix reinforced with aramid fibers, the hose maintains structural integrity at temperatures well beyond the capabilities of standard rubber hoses. The aramid reinforcement provides exceptional tensile strength, allowing the hose to withstand pressures typical of turbocharged and supercharged engines while resisting expansion and deformation.
Measuring 6 x 3.5 x 0.1 inches and weighing just 10.4 ounces, the hose offers a compact profile that fits easily into tight engine bays. The inside diameter ranges from 3 to 3‑1/2 inches, providing ample flow capacity for both turbo and intercooler circuits. The outer silicone layer is formulated to be UV and ozone resistant, extending service life in outdoor or marine environments where exposure to sunlight and salt spray can degrade lesser materials.
Designed to meet and exceed SAE J20 industry standards, the CAC‑300‑350‑HOT model delivers a secure, vibration‑isolating connection between engine‑mounted charge‑air components. Its flexibility accommodates slight misalignments, reducing stress on fittings and preventing premature wear. While the hose is not compatible with fuel or oil, it excels in delivering clean, pressurized air to turbochargers, superchargers, and intercoolers, ensuring optimal boost performance and engine efficiency.

Usage
This silicone turbo hose is ideally suited for a variety of high‑performance and heavy‑duty applications. In marine settings, the hose resists corrosion from saltwater exposure and maintains flexibility in fluctuating temperatures, making it perfect for boat engines equipped with turbochargers or intercoolers. Industrial users will appreciate its durability in harsh factory environments where vibration, heat, and UV exposure are constant challenges.
Custom fabricators and performance enthusiasts can employ the CAC‑300‑350‑HOT hose in bespoke turbo or intercooler piping projects. Its ability to handle slight misalignments means installers can achieve clean, straight runs without the need for additional fittings or complex routing. The hose also works well in racing applications where weight savings and reliable airflow are critical; its lightweight silicone construction reduces overall system mass while delivering consistent boost pressure.
Because the hose is not intended for fuel or oil transport, it should be used exclusively for charge‑air pathways. When paired with compatible clamps and fittings, the hose creates a sealed, vibration‑damped conduit that protects downstream components from heat soak and pressure spikes. Whether installed in a street‑legal performance vehicle, a high‑output marine engine, or an industrial turbo system, the CAC‑300‑350‑HOT provides a dependable solution for delivering clean, pressurized air.

FAQ
What temperature range can the CAC‑300‑350‑HOT hose safely operate in?
The hose is rated for continuous operation up to 350°F (177°C) and short‑term spikes up to 400°F (204°C). This range covers most turbocharged engine applications, including high‑performance street cars and marine engines that experience elevated inlet temperatures.
Can this hose be used for fuel or oil lines?
No. The silicone formulation is specifically engineered for charge‑air use and is not compatible with fuel or oil. Using the hose for fuel or oil could cause swelling, degradation, and potential safety hazards. For fuel or oil lines, select a hose that is explicitly rated for those fluids.
How does the aramid reinforcement improve hose performance?
Aramid fibers, commonly known as Kevlar, provide high tensile strength while remaining lightweight. When woven into the silicone matrix, they prevent the hose from expanding under pressure, maintain shape under heat, and resist abrasion. This results in a more stable airflow path and longer service life compared to non‑reinforced silicone hoses.
Is the hose compatible with standard hose clamps?
Yes. The CAC‑300‑350‑HOT hose is designed to work with common stainless‑steel or aluminum hose clamps that have a 3‑to‑3½ inch inner diameter. For optimal sealing, we recommend using clamps with a minimum clamping force of 150 lb‑in and applying a silicone‑compatible sealant if desired.
What warranty does HPS provide for this hose?
HPS offers a one‑year limited warranty covering material defects. The warranty does not apply to damage caused by improper installation, use with incompatible fluids, or excessive mechanical abuse. Contact our support team with proof of purchase to initiate a warranty claim.
