本SAE推荐实施规程规定了冷却液系统中使用的挠性卡套管或软管与刚性卡套管或管件之间的快速连接接头的最低性能和尺寸要求。本文件适用于以下条件下的汽车和轻型卡车应用:a汽油、柴油、混合动力和电力推进冷却系统。工作压力高达206 kPa（30 psi）。C工作温度为-40°C（-40°F）至125°C（260°F）。快速连接联轴器的作用是将连接器连接到配合端，通常不需要使用工具。 除非另有说明，否则本文件中的要求适用于组装操作中的新连接器。对于现代动力传动系统应用，以下设备的互连通常是冷却组的设计责任:冷却液控制阀、水-空气增压空气冷却器（CAC）、散热器（高温和低温变体）和远程变速器油热交换器（用于加热和冷却功能）。

This SAE Recommended Practice defines the minimum performance and dimensional requirements for quick connect couplings between flexible tubing or hose and rigid tubing or tubular fittings used in coolant systems. This document applies to automotive and light duty truck applications under the following conditions:aGasoline, diesel, hybrid, and electrical propulsion cooling systems.bOperating pressure up to 206 kPa (30 psi).cOperating temperatures from -40 °C (-40 °F) to 125 °C (260 °F).Quick connect couplings function by joining the connector to a mating end form, typically without the use of tools. The requirements stated in this document apply to new connectors in assembly operations unless otherwise indicated.For modern powertrain applications, the interconnection of the following devices is typically the design responsibility of the cooling group: coolant control valve, water-to-air charge air cooler (CAC), radiator (high and low temperature variants), and remote transmission oil heat exchanger (used for both warming and cooling functions).
