That P/N O-ring that your looking for is not available to AW139 operators for field maintenance of the aircraft. as far as Im aware?
The P/N you quote is from the CR&O not the IETP.
Best to get in contact with your local tech rep or Leonardo Customer support.
Check the BT 139-303. I believe that it's a field level maintenance.
