MoreBeer.com and other retailers sell both stainless and ABS versions of a Pluto Gun. They are nice. I’ve got 4 of the stainless versions that I use in place of picnic taps and traditional taps in my keezer.
Yeah, it's right at the tip. Whether it's with picnic taps or with the Pluto Guns I simply keep a spray bottle of Star San/Iodophor (or even tap water would work too) that I squirt into the tip to make sure it's all cleaned out before putting it back in the keezer.That thing is interesting, where does it seal off? If it’s at the tip of the barrel then it could be great, if it’s further back in the barrel then there’s a long tube for gunk to collect and mold to grow in.
