Perlick faucet gushing through shank connection

All equipment is brand new.

Two tested leaky faucets
Perlick Stainless Beer Faucet
Perlick Stainless Creamer Faucet

Beer Tower: Standard two tap tower from MoreBeer

See the picture below. When I apply enough pressure to get beer in the line, the Perlick faucets leak like a sieve. At a few PSI (depicted) it is a steady stream. At 10 PSI it is a geyser and a huge mess.

Ironically, the default stock faucets that came with the tower do not leak. I tried swapping out the coupling gaskets between the stock faucet and the Perlicks, but it still leaks just as bad.

I would assume the fittings are a standard size. They look the same, and screw on snug. I'm not tightening the Perlicks any tighter than the stock faucets.

Any idea what's wrong?

 

Perhaps I should have searched better.

This topic seems to cover the same issue, though it is unclear how anyone has resolved the problem. I'm going to contact MoreBeer.

 

I remember when the original thread (and similar complaints) was running its course. As I recall nearly all of the shanks in question were chromed brass...

Cheers!

 

Today I took my tower and the two faucets to MoreBeer. The guy at the counter was super helpful. The trick was cinching down the faucet really tight with a faucet wrench. We had to use much more force than I would have expected (I was able to tighten the stock faucets by hand). Previously I did not have a faucet wrench; tightening by hand was not enough for the Perlicks.

Props to the folks at MoreBeer for the help.
