Flexible Radiator Reducer Hose — Engineered Solution for Cooling & Thermal Systems

Product Overview

Der Flexible Radiator Reducer Hose is a high-performance, reinforced coolant hose designed for automotive and industrial thermal fluid applications. Built for reliable operation under wide temperature ranges, this hose combines advanced elastomer compounds with engineered reinforcement to deliver consistent pressure handling, Flexibilität, and durability across varying system conditions.

Flexible radiator hoses and reducers are used to adapt between differing diameters in coolant circuits while maintaining flow integrity, pressure resistance, and compliance with SAE J20 industrial standards.

Engineered Materials & Konstruktion

Our flexible radiator reducer hoses are constructed from premium heat-resistant elastomers with tailored reinforcement layers to balance pressure capability and flexibility:

»High-Temperature Elastomer Tube & Startseite – Designed for stable performance in elevated engine bay and industrial environments, with continuous operating temperature from −50 °C to +180 ° C and resistance to heat aging, Ozon, and environmental degradation.

»Reinforcement Layers – Multiple layers of synthetic textiles and/or high-strength braids are incorporated to achieve target working pressure and burst (bursting) strength per size and reinforcement configuration.

»Reducer Design – Provides a controlled transition between hose diameters while maintaining flow continuity and structural integrity.

This construction supports compliance with and exceeds SAE J20 standards for reinforced coolant hoses, ensuring reliable operation in demanding cooling and thermal management systems.

Performance Data — Pressure & Temperatur

Flexible radiator reducer hoses exhibit variable burst pressure and working pressure depending on internal diameter and reinforcement configuration. Typical engineering data are shown below (indicative values):

Actual performance data should be confirmed with specific part numbers and engineering test reports. Custom reinforcement and compound options can be specified for higher performance requirements.

Einhaltung & Standards

The hose design is aligned with SAE J20 series requirements for reinforced elastomer hoses used in cooling systems. SAE J20 defines test protocols and performance criteria for elastomeric cooling system hoses, including thermal aging, burst resistance, dimensional stability, and material properties.

Key aspects validated through material and hose testing:

»Thermal aging resistance at elevated temperatures

»Hydrostatic and burst pressure capacity

»Flexibility and resistance to collapse

»Resistance to coolant additives and environmental factors

These elements ensure the hose meets industrial expectations for durability, safety, and lifecycle performance in automotive and industrial systems.

Engineering Test & Validierung

Performance validation typically includes rigorous tests such as:

»Hydrostatic & Burst-Test

Hoses are pressurized beyond expected working pressures until structural failure to determine burst limits, which for reinforced radiator reducer hoses can range up to ~16 MPa depending on size and reinforcement.

» Thermal Endurance Testing

Continuous exposure to high temperature environments to assess elastomer aging, mechanical property retention, and dimensional stability over time.

»Dynamic Flex & Fatigue Testing

Simulates vibration, flexing, und thermische Zyklen, die im realen Betrieb beobachtet wurden, um die langfristige Gebrauchstauglichkeit ohne Rissbildung zu bestätigen, Delaminierung, oder Festigkeitsverlust.

»SAE-Konformitätstests

Beinhaltet Tests gemäß SAE J20-Protokollen zur Überprüfung der physikalischen Eigenschaften, Alterungsleistung, und Maßtoleranzen, die für Kühlsystemschläuche erforderlich sind.

Zur Unterstützung können technische Prüfberichte zur Verfügung gestellt werden OEM-Zulassungen, Qualitätsaudits, und Systemqualifizierung.
