Inflator Base for Diluent or Oxygen manual inflators.
Replacement part for Inspiration, Evolution and Evolution+
Please note when dis-assembling: the lower thread is left-handed and screws into the bottom locking ring anti-clockwise, tightened with a 13mm Hex key.

The upper thread (for the inflator top locking ring) is a conventional clockwise thread. The reason for the opposite threads is to avoid loosening the base fitting when undoing the top ring when cleaning the inflators.
