Draft Hardware Compatibility & Cleaning Schedule

Keep every pour tasting like the brewery taproom.

01
Verify Ball-Lock Disconnect Colors (Gray = Gas, Black = Liquid)
Never force a black liquid disconnect onto the angled gas post of a mini-keg spear.
02
Use Self-Closing Faucet Springs Inside Tight Fridges
Prevents a bumped door shelf from cracking the tap handle open.
03
Clean Kegerator Lines Every 14 Days
Unscrew the faucet from the 7/8"-14 shank and pump alkaline line cleaner through.
04
Lubricate Silicone O-Rings With Food-Grade Keg Lube
Stops slow CO2 headspace leaks around the cap threads.

Questions

Does the Taprite 1842G cleaning kit require CO2 to flush the beer line?

No—it uses a built-in hand pump on top of the 1-quart bottle and threads directly onto the beer faucet shank.

Will the ProMaker ball-lock spear fit a 64 oz or 128 oz TMCRAFT growler?

Yes, both use the standard 33mm inner / M35×1.5 stainless mini-keg neck thread; simply trim the silicone dip tube to match your keg height.
