Went to install it, all is well except the GAS Inlet has straight male threads that looks like the connection need a rubber washer.
However I need to connect a black pipe to it, with a drip leg and a TEE . The Short Yellow CSST will connect to the TEE and connect to the shut off valve
which is connected to the main gas supply. The Inlet is 3/4 and the supply is 3/4. Is there a adapter that can connect to the male threads on the inlet and
allow me to connect the 3/4 Black Pipe to the adapter

If it is straight threads, then, no, there is no adapter.
