SAE J3143的范围将涵盖用于在汽车空调系统中容纳和循环润滑剂（PAG、POE压缩机油）、液体和气态R-134a、R-152a或R-1234yf制冷剂的非金属管路组件。SAE J3143还将提供SAE J2727移动式空调系统制冷剂排放图中使用的必要软管渗透值。组件的设计应尽量减少制冷剂的渗透和系统的污染，并在-30至125°C的温度范围内工作。具体施工细节由用户和供应商商定。 图1 显示了一个典型的TXV空调系统。

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. Figure 1 shows a typical A/C system with TXV.
