Storz coupling sizes: DN and lug distance
Why two numbers describe a Storz coupling, which heads connect to each other, which DN fits which lug distance, and how to read our article numbers.

Storz couplings are symmetrical: two identical heads with lugs connect with a quarter turn, without male and female parts. The size of a Storz head is set by the distance between the lugs. DN 25–100.
Delivery across Bulgaria by Econt and Speedy and across the EU — delivery terms.
We can assemble the hose with couplings and pressure test it — service.
Each size is a separate item with its own article number. Searching the site by article number takes you straight to the row.
