Wennstrom offers two types of loading couplings: API and 3” dry break couplings. The latter are used for loading on the Swedish market only.
Wennstrom has also developed a special flat bottom API loading coupling to meet the requirement of a completely empty coupling after discharge. The couplings can be equipped with or without sight glasses and handles.
For really tight places we have an extra short API coupling with a brass ring to avoid friction between the aluminium coupling on the loading arm and the aluminium coupling on the road tanker.
