J2044_200209
This SAE Recommended Practice defines standard tube end form dimensions so as to guarantee interchangeability between all connector designs of the same size and the standard end form. This document also defines the minimum functional requirements for quick connect couplings between flexible tubing or hose and rigid tubing or tubular fittings used in supply, return, and vapor/emissions in fuel systems. This document applies to automotive and light truck applications under the following conditions: a Gasoline and diesel fuel delivery systems or their vapor venting or evaporative emission control systems. b Operating pressure up to 500 kPa, 5 bar, (72 psig). c Operating vacuum down to –50 kPa, –0.5 bar (–7.2 psi). d Operating temperatures from –40 °C (–40 °F) to 115 °C (239 °F). Quick connect couplings function by joining the connector to a mating tube end form then pulling back to assure a complete connection.
