This KegLand faucet wrench does the following:
• Tightens Nukatap and Intertap tower shank inner nuts.
• Tightens Nukatap or Intertap 4" shank holding nuts (but not other 4" shanks)
• Tightens and removes all Faucet Attaching Nuts, Nukatap and all other brands.
• Tightens and loosens KegLand brand regulator C02 nuts (does not fit Taprite and other brands)
• Tightens and loosens KegLand MFL nut and barb fittings
• Opens a beer bottle
It also claims to fit DuoTight fittings to open the collar to release tubing. We have found this claim a bit dubious, as the wrench is too thick to fit around a DuoTight fitting.
