Jplayer- you're right- the propane suppliers don't know nor care about what product they sell. I'm in the Phila are & can find only 1 vendor which can verify they sell HD-5 propane. All the other vendors say "propane is propane- what's the difference?".
I"ve notice since Intrupa & SMH have become 1 and now it's TVH- their model J regulators don't seem to last as long due to this reed valve issue. I can only assume they're making a cheaper product.
