Ok so i just recieved this scba tank i bought on ebay a week or so ago, now im looking to see what type of adapter i need so i can fill my impact up. Any and all helps is much appreciated
If you take that gray piece off, you should be left with threads that look like the fitting on the right.
You'll need... a CGA 347 style fitting. They come in hand tight or wrench tight. The wrench tight is pictured on the left. a blender valve a length of hose and related adaptors a foster fitting It's also very nice to add a 2-1/2" gauge to your system but, it's not needed.
I do all my shopping for fittings at Nothshorecompressor.com but, there's plenty of other sources out there that will have what you need. Also, I have everything but the bleeder up for sale right now in the classifieds. Check your PM's Tom
