FM50 APR CONVERSION TO 40mm DIN CONNECTION

Q:  When converting the FM50 respirator to the 40mm standard NATO DIN connection do you need any filter canister gaskets?

A: The  Avon Protection 40mm standard NATO DIN connection conversion kit (P/N 601949) is supplied with a canister gasket already installed in each specific (LH & RH) assemblies.
