Quick Connect Fluid Coupling Specification for Coolant System Interconnect
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.
