This document provides technical specifications and applications for various types of hoses used in air brake systems, specifically focusing on materials such as Polyamide (PA 12) and Polyurethane. The document outlines the characteristics, dimensions, and compliance with automotive standards, particularly DIN 73378/74324.
- PA 12 PHLY: A semi-flexible, plasticized polyamide with excellent resistance to temperature and light, high burst pressure, and shock resistance at low temperatures. It is designed for automotive air brake systems and complies with DIN 73378/74324 standards. Available in black.
- PA 12 PHL: A flexible polyamide, plasticized and light-stabilized, offering excellent resistance to aging and dimensional stability at high temperatures. It has low plasticizer migration and is available in multiple colors (blue, yellow, red, black).
- Characteristics: Polyurethane hoses are chemically originated, offering excellent resistance to humidity and low temperatures, light stabilization, and high flexibility. However, they are not homologated for certain applications.
The document provides detailed dimensions for various hose types, including inner and outer diameters, weight, bending radius, and pressure ratings at 20°C. Tolerances are specified for wall thickness, outside diameter, and weight.
The primary application for these hoses is in the automotive sector, specifically for air brake systems. The document includes a table showing pressure values as a percentage relative to temperature, indicating the operational range from -40°C to +80°C.
