SAE J2494-3 Test for Non-Metallic Push-Out Connectors Used in Vehicle Air Brake Systems

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of SAE J2494-3 testing. SAE J2494-3 is a standard developed by the Society of Automotive Engineers (SAE) that specifies performance requirements for non-metallic air brake pipes and push-connect fittings used in vehicle air brake systems. This standard applies specifically to assemblies made from SAE J844 types A and B nylon tubing and SAE J2494 type fittings.

The purpose of this SAE Standard is to establish uniform performance criteria and methods for testing SAE J844 air brake piping and push to connect pipe fittings used in vehicle air brake systems.

SAE J844 type A and B nylon tubing are plastic materials commonly used in automotive air brake systems. Type A tubing is made of a single-layer nylon material, while type B tubing is made of a multi-layer structure that includes an outer nylon layer, a middle adhesive layer, and an inner nylon layer. The multi-layer construction of type B hose provides greater resistance to abrasion, kinking and bursting.

SAE J2494 type fittings are specifically designed for use with non-metallic tubing and are used to connect tubing to other components within an air brake system. These fittings are made from plastic or composite materials and are available in a variety of configurations, including compression, barbed, and bass-connect designs.

The requirements set out in SAE J2494-3 cover several key aspects of non-metallic air brake pipes and push-to-connect fittings used in vehicle air brake systems, including:

  • explosive power;
  • Tensile strength;
  • Resistance to bending and abrasion;
  • Resistance to degradation caused by exposure to ozone, sunlight and other environmental factors;
  • Compatibility with various types of brake fluid;
  • Performance in high and low temperature conditions;
  • resistance to corrosion;
  • Ease of insertion and removal.

Compliance with SAE J2494-3 is important to ensure the safety and reliability of non-metallic air brake pipes and push-rod assemblies used in vehicle air brake systems. By adhering to these standards, manufacturers can ensure that their products meet the highest levels of quality and performance.
