Identify it on the keg

Which spear is in the keg?

Lists by brewery or brand often contradict each other, because the spear belongs to the keg fleet, not to the brand. A look at the keg and a calliper is quicker and more reliable.

Round and flat

Flat, round flange of Ø 74.5 mm, one valve. A safety triangle on the body.

Triangular

Flat flange with three lobes, Ø 70 mm. Identical to type A inside, but not outside. That is why it needs a different keg coupler.

Round, two valves

Round flange of Ø 74.5 mm, the same size as type A. Here the shape decides, not the calliper.

Sankey, no flange

No flange resting on top; the spear sits in the keg neck. Body Ø 48.1 mm, small opening Ø 19.3 mm.

Nothing above the keg neck

The body sits in the keg neck and is flush with it. Ø 53.7 mm across the locking lugs, opening Ø 38.9 mm. Threaded, or threadless with a retaining ring.

Watch out at 68 mm. Keg Exchange describes a version of the flat spear with a 68 mm instead of a 74.5 mm flange, which always has a left-hand thread. With rough measuring it is easily mistaken for a Sankey spear. AOBAOSI does not make this version.

Distribution

Where each system is common

Empirical values from more than a thousand assignments in thirteen countries, compiled by our European partner Keg Exchange. They do not replace a check on the keg: the same brand can carry different spears depending on keg size, year of manufacture, country and beer.

System	Common in	Note
A Flat spear	Germany, Austria, much of Europe	So widespread in Germany that the trade often does not even mention it.
S EU Sankey spear	Belgium, Netherlands, parts of France, Czech Republic	The leader by volume in the Czech Republic.
D Sankey spear (US Sankey)	North America, United Kingdom, export kegs	Threadless design, mainly from the British and American markets.
G Triangular spear	United Kingdom, Austria, Baltic states	Not a purely British design. Very rarely used in Germany, somewhat more common in Austria.
M Combi spear	Poland, Czech Republic	Used by only a few breweries in Germany.
