What Intelligent Keg Filtering Tools Actually Do
Intelligent keg filtering tools match kegs to the correct couplers and dispense equipment, so the fitting is more likely to work first time. At Keg Drop, we use this filtering to help confirm compatibility between each keg and your tap system.
Keg Coupler Compatibility: Why the Wrong Fitting Ruins the Pour
A-type, Sankey, Grundy and U-type fittings look similar but do not interchange, so check your system before you buy.
If your coupler is A-type, the A Type 5l cleaning bottle cap fits it. Sankey users want the Sankey 5l cleaning bottle cap, Grundy users the Grundy 5l cleaning bottle cap, and U-type users the U Type 5l cleaning bottle cap.

Frequently Asked Questions
What is the difference between a keg filter and a beer filter?
A beer filter removes yeast, hop particles and sediment from the liquid itself, usually through a cartridge or plate with a set micron rating. A keg filtering tool works on the equipment side: it narrows the kegs, couplers and dispense systems that will actually fit together. One changes what is inside the beer, the other stops you buying a keg that will not connect to your PerfectDraft, BLADE or Brewlock setup.
How can I check which coupler fits a keg?
Start with the keg type and fitting, then match it to a coupler: Sankey, Grundy and U-type each need their own connection, and the cleaning caps in our range are built to match. A keg compatibility checker does this filtering for you. If you are unsure, ask before ordering rather than guessing, because a mismatched coupler means no pour at all.
Can filtering tools help prevent ordering incompatible dispense equipment?
Yes. Filtering by coupler before you browse helps you check that a keg will connect to your system before you order.
Getting the fitting right is the difference between a clean pour and a flat, foamy mess. Keg Drop matches every keg to your coupler through our filtering, with nationwide delivery, free collection from our Macclesfield depot, and easy returns on empty kegs. Get started with Keg Drop and pour with confidence from the first pint.
