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: a Gasoline, diesel, hybrid, and electrical propulsion cooling systems. b Operating pressure up to 206 kPa (30 psi). c Operating 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). This document is intended to provide a recommended practice for the construction details for the male and female coolant quick connects. It also provides performance and dimensional specifications for quick connect devices designed specifically for coolant systems interconnect. These types of connections have increasing usage worldwide without the benefit of common performance and dimensional standard definition to guide their use.
