Flat (A-type), EU Sankey (S-type) and combi spears (M-type) in stainless steel – developed and produced for 26 years, shipped from the EU warehouse in Miastko. No waiting for an overseas sailing, no customs clearance, with a German contact.
Range
The design at the keg neck decides which coupler fits. Here are the five that matter in Europe – each with its own page, dimensions and spare parts list.
The drawings are schematic top views for telling the systems apart, not scale representations. Dimensioned drawings are on the individual type pages.
Engineering
Manufacturers explain the systems in words and leave out the dimensions. We do it the other way round.
We concentrate entirely on 2″ × 14 TPI – the European market standard. Not a range spread across eight secondary threads, but depth in the standard: available immediately, in every type, with the matching spare parts. Why this thread is the better choice.
Square seals, O-rings, springs, valve discs and retaining rings – singly and as a set, assigned to type and year of manufacture. The retaining ring is used once only, without exception.
The connection dimensions of keg necks and keg connection parts are laid down in DIN 3542, the matching couplers in DIN 32677. The container standards DIN 6647-1 and -2, by contrast, cover pressure classes, not spear types.
Quality
Every spear goes through a leak test. Production is certified to ISO 9001, the materials used are approved for food contact and meet FDA and CE requirements.
Materials
Forever chemicals, as the press calls them. The substance group also includes PTFE – Teflon in everyday terms – and PTFE-based friction coatings on threads are common in the trade. Not with us, and voluntarily so, well ahead of regulation. We are taking new paths towards a sustainable future.
What already applies today, what is still to be decided – and why that matters for a keg fleet
Logistics
The difference between a spear from China and a spear from Miastko is not the data, it is eight weeks.
What that means in practice – and what we do when the spear length does not fit
