Technical note: The supplied image confirms the general quick-connect fuel-fitting structure and the stated 3/8-inch size, but it does not provide enough information to establish the exact thread, O-ring material, pressure rating, temperature range or vehicle fitment. Those specifications should be confirmed before publication as fixed technical claims.
The 3/8 inch fuel line fitting is intended for compatible fuel-line tubing and connection systems. Tube outside diameter and mating connector specifications should be verified before ordering.
3/8-inch automotive fuel-line fittings are commercially available in different configurations, including quick-connect, barb and threaded adapter combinations.
The quick-connect structure allows the mating fuel-line component to be connected without relying solely on a conventional threaded joint.
For an automotive fuel line quick connect fitting, the locking mechanism, mating profile and sealing structure must correspond to the receiving component.
The supplied product uses a relatively compact inline structure, which can be useful where fuel-line routing space is limited.
The final length, end configuration and mounting geometry can be adjusted according to the approved product drawing.
Used for compatible fuel-line repair and replacement applications where a 3/8-inch quick-connect interface is required. The fitting can help connect replacement fuel-line sections without changing the complete fuel-line assembly.
Suitable for connecting compatible fuel-system components such as fuel rails, fuel hoses and related adapters where the specified 3/8-inch connection geometry matches the application.
Commercial automotive products use 3/8-inch quick-connect fittings in fuel-line and fuel-rail connection applications.
We can evaluate the fitting according to the actual mating components rather than relying only on nominal size.
Key parameters include:
Fuel-line outside diameter
Quick-connect profile
Thread specification
Connection length
Seal specification
Installation space
Mating component
Required quantity
This helps establish the correct specification for an OEM fuel line fitting project.
We support automotive fitting programs from sample development to repeat bulk production.
As an automotive fuel fitting supplier, we can coordinate product specifications, packaging, inspection requirements and production quantities according to the approved purchasing specification.
Custom Dimensions from Drawing: Available
For a custom fuel line quick connect fitting, customers can provide:
2D engineering drawing
3D CAD file
Original fitting sample
Fuel-line diameter
Thread specification
Overall length
Connection geometry
Seal requirement
Surface-treatment requirement
The approved drawing or sample can be used as the production reference.
If the original fitting is available but the technical drawing is incomplete, we can evaluate the sample for dimensional matching.
For an OEM automotive fuel fitting, providing both the original fitting and mating hose or connector information is recommended where possible.
Fuel-line fittings require controlled connection dimensions because the fitting interfaces directly with the fuel delivery system.
Our inspection focus can include:
Overall dimensions
3/8-inch connection dimension
Quick-connect profile
Thread dimensions
Thread condition
Locking structure
Sealing interface
Surface condition
Burr inspection
Dimensional tolerance
Drawing-to-sample comparison
Batch consistency
Where required, additional inspection or pressure-testing criteria can be established according to the final approved specification.
We provide 3/8 inch fuel line fittings for B2B automotive component sourcing programs requiring defined connection specifications and repeat production.
For wholesale fuel line fittings, we can coordinate:
Fitting configuration
Tube size
Thread standard
Connection profile
Material
Surface finish
Seal specification
Packaging
Quantity
Inspection requirements
For larger purchasing programs, bulk automotive fuel fittings can be supplied according to the approved specification.
As a fuel line fitting manufacturer, we can also evaluate related automotive pipe fittings and custom connector components for broader sourcing requirements.
This product can be connected with relevant internal categories:
Auto Pipe Fittings
Auto Parts
Powertrain Drivetrain Systems
Sensors Electrical Ignition Systems
Water Pipe Fittings
The most directly relevant internal-link category for this product because the component functions as a specialized automotive fluid-line connector.
Useful for broader navigation toward engine and powertrain components.
Provides a higher-level category path for customers sourcing additional automotive replacement components.
Before ordering a 3/8 inch fuel line fitting, we recommend confirming the following information:
Confirm that the required fuel hose or tubing uses the intended 3/8-inch connection specification.
Nominal diameter alone does not guarantee compatibility. The mating connector profile and locking structure should also be confirmed.
If the fitting includes a threaded end, specify the required thread standard and size rather than relying only on the 3/8-inch designation.
For fuel-system applications, the seal material should be selected according to the fuel type, operating temperature and application requirements.
Providing the original part number, vehicle application, fuel-system component or original sample can improve fitment evaluation.
For wholesale and bulk purchasing, specify the expected order quantity, individual packaging and carton requirements before quotation.
This product is specified for a 3/8-inch fuel-line connection. The exact mating connector profile should still be confirmed because 3/8-inch fuel fittings are available with different connection and thread configurations.
Yes. A custom fuel line quick connect fitting can be developed according to a technical drawing, CAD file or original sample. Connection dimensions, thread configuration, material and sealing requirements can be evaluated according to the application.
Yes. We support bulk automotive fuel fittings and wholesale B2B procurement. Customers can provide the required configuration, quantity, packaging requirements and application information for quotation.
