Lloyd’s Register certification
The FD85 Series carries a Lloyd’s Register certificate for fire conditions outlined in API 16D and EUB Directive 36. These assemblies are specified to maintain pressure in the connected state when exposed to 700C / 1,300F for five minutes, when both mating halves are Danfoss FD85 Series thread-to-connect couplings.
Where FD85 is commonly used
