Sanke Keg Coupler Guide - Beer Brand Chart

Sanke Keg Coupler Guide - Beer Brand Chart

Not every commercial keg uses the same Sanke keg coupler. The correct coupler must match the valve installed in the keg. Using the wrong keg coupler can prevent the keg from tapping correctly and may damage the keg valve or coupler.

Use this Sanke keg coupler guide to compare A, D, G, M, S and U System couplers and identify the coupler commonly used by popular breweries and beer brands.

Important: These are common compatibility examples, not guaranteed matches. A brewery may use different keg valves based on keg size, packaging location or distribution market. Confirm the required Sanke coupler with the brewery, keg supplier or distributor before ordering.

D System Keg Coupler

The D System keg coupler is also known as an American Sankey or US Sankey coupler. It is the most common commercial keg coupler in Canada and the United States.

Common D System brewery and beer examples include:

  • Molson Canadian
  • Coors Light
  • Labatt Blue
  • Budweiser and Bud Light
  • Alexander Keith’s
  • Moosehead
  • Steam Whistle
  • Sleeman
  • Corona and Modelo
  • Sam Adams
  • Sierra Nevada

Choose a D System keg coupler only after confirming that the keg has a D System valve.

S System Keg Coupler

The S System keg coupler is commonly called a European Sankey coupler. It resembles the D System but uses a longer, narrower probe.

Common S System brewery and beer examples include:

  • Heineken
  • Stella Artois
  • Pilsner Urquell
  • Beck’s
  • Amstel
  • Leffe
  • Erdinger
  • Newcastle
  • Strongbow
  • Murphy’s

D System and S System couplers may look similar, but they are not interchangeable.

A System Keg Coupler

The A System keg coupler is often called the German Slider because it slides horizontally onto the keg valve instead of twisting into place.

Common A System brewery and beer examples include:

  • Paulaner
  • Spaten
  • Warsteiner
  • Weihenstephan
  • Ayinger
  • Hoegaarden
  • Carlsberg
  • Chimay
  • Bitburger
  • Krombacher

A System couplers can be taller than standard D System couplers. Check the available clearance inside the kegerator before connecting the beverage line.

G System Keg Coupler

The G System keg coupler is also known as a Grundy coupler. Its keg-valve connection has a distinctive shape with three flattened sides.

Common G System brewery and beer examples include:

  • Boddingtons
  • Grolsch
  • Innis & Gunn
  • Fuller’s
  • Old Speckled Hen
  • Anchor Steam
  • Wexford Irish Cream Ale

M System Keg Coupler

The M System keg coupler has a slider-style body similar to an A System coupler, but its probe configuration is different.

Common M System brewery and beer examples include:

  • Schneider
  • Aventinus
  • Einbecker
  • Veltins
  • Żywiec

Do not substitute an A System coupler for an M System coupler based on appearance alone.

U System Keg Coupler

The U System keg coupler is also known as a UEC or Guinness keg coupler.

Common U System brewery and beer examples include:

  • Guinness
  • Harp
  • Smithwick’s
  • Kilkenny
  • Magners

Confirm the valve used on the specific keg before purchasing a U System coupler for Guinness or another Irish beer brand.

How to Identify the Correct Keg Coupler

The safest way to select a Sanke keg coupler is to ask the keg supplier, brewery or distributor which coupler system the keg requires.

Before ordering, confirm:

  • Beer or beverage brand
  • Brewery or beverage company
  • Keg size
  • Country or market where the keg was filled
  • Required coupler system
  • Available height inside the kegerator

Do not select a keg coupler based only on the beer brand. A brewery may use different keg valves for different keg sizes or distribution markets.

What Connects to a Sanke Coupler?

A Sanke keg coupler connects the keg to the gas and beverage lines in a draft beer system.

A standard coupler normally has:

  • A gas inlet connected to the CO2 regulator
  • A beverage outlet connected to the beer line
  • A probe that engages the keg valve
  • A handle used to tap and untap the keg
  • A pressure-relief valve on compatible models

Tailpieces, hex nuts, washers, check valves and hose fittings may be required depending on the coupler and draft beer system.

Standard or Low-Profile Keg Coupler?

A standard Sanke coupler works for most draft installations. A low-profile keg coupler may be required when there is limited clearance above the keg inside a kegerator.

Measure the available space above the keg before ordering. A tight beer-line bend can restrict flow or kink the tubing.
