4" Aluminum Tank Cabinet Dummy Weld-On Adapter Blank

Dixon identifies AL4051-BORE specifically as the 4" fuel-delivery version of its tank cabinet dummy weld-on adapter blank. This distinguishes it from Dixon's separate 400AWSPAL blank, which is intended for vapor-recovery cabinet service.

That distinction matters when laying out petroleum transport equipment because the fuel-delivery and vapor-recovery positions serve different functions within the cabinet. Confirm the intended cabinet location before fabrication so the correct blank is installed in the correct opening.

The AL4051-BORE is intended to be welded into the tank cabinet rather than installed as a removable threaded or clamped component. Once incorporated into the cabinet, it becomes part of the fabricated equipment structure.

Fit-up and positioning should be established before welding begins so the blank remains correctly aligned with the surrounding cabinet geometry. Appropriate aluminum welding practices should be used for the mating material and fabrication process.

The component is supplied as a dummy adapter blank rather than as a finished delivery valve, coupler, or threaded outlet. Its role is to provide the designated cabinet adapter location during fabrication or equipment configuration.

This allows builders or service operations to establish the required cabinet arrangement without substituting an unrelated fitting. The final assembly should be reviewed against the intended fuel-delivery layout before the equipment is returned to service.

Before welding, verify the 4" opening, surrounding cabinet clearance, and orientation of the blank within the fuel-delivery section. Proper fit-up helps avoid distortion or misalignment during fabrication.

After welding, inspect the joint and surrounding cabinet structure for complete attachment and visible fabrication defects. The finished installation should be checked as part of the overall petroleum transport equipment inspection before use.
