NOTES

  1. Where an in-place assembly with round flanges must be identified, and the diameters "A" & ”C" cannot be measured, the circumference of the bellows FLANGE, the number of flange bolt holes and the bellows length an be used for identification.

  2. In the table, (NA) refers to “Natural Aspirated", (T) refers to “Turbocharged" and (TA) refers to Turbo-charged-Aftercooled" Engines.

  3. Certain installations may be set up more than one way. See sketch above, and items marked ’ in the table.

  4. Special designs such as Weld-Necks, V-Band Clamp Fittings and Mixed-Size Flanges can be furnished on special order. Please note A, 8, C, & E for non-standard units and combinations. Please note each end for A, 8, C, and E when ordering.

  5. To prevent damage to turbochargers and bellows - Disconnect one flange and block airflow during all moving operations.
