I paired this faucet with several other parts to make a keg beer faucet, and I won't go back to beer line and picnic taps. It's easier to maintain and the faucet is beautifully made. 

This was recommended by a friend and well worth the $$$.

I have 3 Intertap faucets that I have been using for about 7 months now. I've run several kegs though them with no issues--no leaks, no sticking, nothing. I love that Intertaps are the forward-sealing design similar to Perlicks but at a fraction of the cost. I also love how easy they are to disassemble for cleaning and that the faucets can easily be changed from a standard faucet to a stout faucet, to a growler filler, to a ball lock connection and back again with ease. These faucets can be whatever you need them to be and are well-built. The only "complaint" I have is that one of my faucets, just above the adapter threading, there was a curled metal burr about 0.5" long which was not removed during machining. I pulled it out before use and checked for rough areas (which I didn't find) and all was well. I will be purchasing an additional 3 of these faucets to complete my 6-tap keezer. Stop shopping and just buy these! You won't be disappointed! And Williams Brewing has the best price.

Not at present, but thanks for the suggestion.

We are not sure, we do not have an old Perlick 425 to test this with.
