Description
Product Overview
The HPS Silicone High Temperature 4‑Ply Reinforced Elbow Coupler Hose is engineered for demanding automotive and industrial applications where reliability under heat and pressure is paramount. Constructed from premium silicone polymer reinforced with four layers of high‑strength fabric, this hose maintains structural integrity at temperatures that would degrade standard rubber hoses. The 75 psi maximum pressure rating ensures a secure seal in turbocharger, intercooler, and custom intake systems, while the 4‑inch leg length on each side provides ample flexibility for routing in tight engine bays.
Designed to meet and exceed SAE J20 specifications, the hose features an inside diameter ranging from 1.12 in to 1‑1/4 in, allowing for a broad spectrum of flow rates. The outer surface is treated to resist UV radiation and ozone degradation, extending service life even in outdoor marine environments. The black coloration not only offers a professional appearance but also helps conceal any surface contaminants that may accumulate during installation.
Installation is straightforward thanks to the precision‑engineered coupler ends that fit standard 1/4‑inch barb fittings. The hose’s flexibility enables easy bending around obstacles without kinking, reducing the need for additional fittings or adapters. Whether you are fabricating a high‑performance turbo system, upgrading an intercooler circuit, or constructing a custom cooling loop for marine engines, this hose delivers the performance and durability required for demanding conditions.
Usage
In automotive performance builds, the HPS silicone hose excels in turbocharger and supercharger applications where exhaust‑driven heat can exceed 200 °C. Its high‑temperature resistance ensures that the hose does not soften, swell, or lose shape, preserving the intended boost pressure and preventing leaks that could lead to engine damage. The hose is also ideal for intercooler piping, where it must handle rapid temperature fluctuations as air is cooled and then reheated.
Marine enthusiasts benefit from the hose’s UV and ozone resistance, making it suitable for engine cooling systems on boats that are constantly exposed to sunlight and salty sea air. The robust silicone material resists cracking and brittleness caused by prolonged exposure to harsh environmental conditions, providing a reliable coolant conduit for both inboard and outboard engines.
Industrial users can employ the hose in custom pneumatic or hydraulic circuits where high temperature and pressure are common. Its chemical resistance to most non‑oil fluids ensures safe operation in applications such as air‑to‑air heat exchangers, compressed air lines, and water‑based cooling loops. DIY hobbyists will appreciate the hose’s ease of cutting and fitting, allowing for rapid prototyping of custom intake manifolds, radiator upgrades, and experimental cooling solutions.
