Confirm Before Order

  • Confirm seal compound and compatibility with the actual cargo.
  • Confirm the emergency relief setting and flow rating for the supplied assembly.
  • Confirm the drawing revision, mating tank opening and mounting arrangement; the family table gives 20 in across several variant sizes.
  • Confirm which vents, sensor, dip tube, key, latch, hoop and base are included rather than optional.
  • The nominal product suffix is 500, while the drawing appears to show Ø510 and Ø550 mm.
  • Three small elevation callouts at the right are not reliably legible.
  • The illustrated dedicated vent has no separately mapped inventory code; confirm its specification with the cover.
