Product Code:SAE J2044
Title:Quick Connect Coupling Specification for Liquid Fuel and Vapor/Emissions Systems
Issuing Committee:Fuel Systems Standards Committee
Scope: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 掳C (脨40 掳F) to 115 掳C (239 掳F).Quick connect couplings function by joining the connector to a mating tube end form then pulling back to assure a complete connection. The requirements stated in this document apply to new connectors in assembly operations unless otherwise indicated. For service operations, the mating tube should be lubricated with SAE 30-weight oil before re-connecting.NOTE--New connector designs using the same materials as previously tested connectors may use the original results as surrogate data for 7.1, 7.2, 7.3, and 7.4.Vehicle OEM fuel system specifications may impose additional requirements beyond the scope of this general SAE document. In those cases, the OEM specification takes precedence over this document.
