Non-Metallic, Non-Reinforced Automotive Air-Conditioning Refrigerant Line Assembly Requirements

<div class="section abstract"> <div class="htmlview paragraph">The scope of SAE J3143 will cover non-metallic line assemblies intended for containing and circulating lubricant (PAG, POE compressor oils), liquid, and gaseous R-134a, R-152a, or R-1234yf refrigerant in automotive air-conditioning systems. SAE J3143 will also provide the necessary hose permeation values used in SAE J2727 mobile air-conditioning system refrigerant emission charts. The assembly shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to 125 °C. Specific construction details are to be agreed upon between user and supplier. <span class="xref">Figure 1</span> shows a typical A/C system with TXV.</div> </div>
