HPS HTSER45-075-125-BLK Silicone High Temperature 4-ply Reinforced 45 degree Elbow Reducer Coupler Hose, 100 PSI Maximum Pressure, 4″ Leg Length on each side, 3/4″ > 1-1/4″ ID, Black

Description

Product Overview

The HPS HTSER45-075-125-BLK silicone high temperature 4‑ply reinforced 45 degree elbow reducer coupler hose is engineered for the most demanding automotive and industrial environments. Constructed from premium silicone, the hose delivers exceptional flexibility while maintaining a robust 5 mm nominal wall thickness that resists deformation under pressure. With a maximum operating pressure of 100 PSI, the hose meets and exceeds SAEJ20 standards, guaranteeing reliable performance in high‑heat, high‑stress applications such as turbocharger and intercooler systems, marine cooling loops, and custom industrial piping.

Key specifications include an outside diameter ranging from 1.15″ to 1.66″, a 3/4″ to 1‑1/4″ inside diameter reduction, and a 4‑inch leg length on each side for easy routing and secure connections. The black silicone exterior provides UV and ozone resistance, extending service life even when exposed to harsh environmental conditions.

Usage

This hose excels in a variety of real‑world scenarios. Performance enthusiasts building custom turbo or supercharger setups will appreciate the hose’s ability to handle extreme temperatures while maintaining a tight seal. Intercooler manufacturers rely on its consistent diameter and pressure rating to ensure efficient charge cooling. In marine applications, the hose’s UV resistance protects against sun‑induced degradation, making it ideal for engine cooling, bilge pumps, and seawater‑exposed circuits. Industrial users can integrate the hose into high‑temperature coolant loops, heat exchangers, and pneumatic systems where durability and chemical resistance are paramount.

Because the silicone material is not compatible with fuel or oil, the hose is best suited for coolant, water, and air applications. Its flexible yet sturdy construction allows for easy bends around tight engine bays, while the reinforced 4‑ply layers prevent kinking and maintain flow integrity under dynamic loads.

FAQ

Is this hose compatible with fuel or oil?

No. The silicone material is not designed for direct contact with fuel or oil. It is intended for coolant, water, and air applications only.

What is the maximum operating temperature?

The hose is rated for high‑temperature environments typical of turbocharger and intercooler systems, comfortably handling temperatures up to 200 °F (93 °C) without loss of integrity.

Can I use this hose in a marine environment?

Yes. The hose’s UV and ozone resistance makes it well‑suited for marine applications where exposure to sunlight and saltwater spray is common.

What fittings are recommended for installation?

Standard hose clamps and barbed fittings that match the 3/4″ to 1‑1/4″ ID specifications are recommended. Ensure clamps are tightened to the manufacturer’s torque specifications for a leak‑free seal.

How does the warranty work?

The hose comes with a two‑year manufacturer warranty covering defects in material and workmanship. If a defect arises, contact our support team with the purchase details for a replacement or refund.
