The right accessories for your AdBlue® system

〰️

Dispensing hose – length & type

The dispensing hose DN 19 is the standard for most AdBlue® nozzles and pumps. By the metre (€14.50/m) for individual lengths or ready-made as a 4 m hose (€56). DN 19 = 19 mm internal diameter, suitable for all 3/4" and 1" connections. For pumps with a high flow rate (over 40 l/min), DN 25 is more sensible – then request the hose separately.

🔩

Choosing connections & fittings correctly

Hose connections join the hose and the pump outlet. Straight connections for a direct outlet, 90° connections for space-saving installation in tight housings. Pay attention to the thread system: union nut (ÜWM) or nipple, 1" or 3/4". PIUSI parts fit all PIUSI pumps and Suzzarablue systems.

🛢️

Drum connectors for 200 L drums

The PIUSI AF2 drum connector (€63) is screwed into the drum's bung and enables the direct connection of the pump. Four thread sizes available: 2" BSP (standard thread), 2"B, 2" 70×6 (Mauser/coarse thread) and 56×4 (buttress). The correct size depends on the drum type – if in doubt, measure the thread or ask the drum manufacturer.

🔗

SEC couplings for IBC containers

The SEC coupling with a DN19 connection (€61) enables a drip-free connection to IBC containers with an SEC outlet valve – no AdBlue® escapes when disconnecting. The SEC suction tube 865 mm (€63.50) as a matching dip tube for the IBC container. The PIUSI DRUM suction tube (€87) in 2"BSP or 56×4 for various drum openings.

🧲

Elafix magnetic adapter – what is it?

The Elaflex Elafix 40 magnetic adapter (€28) is fitted into the vehicle's AdBlue® filler neck and enables the automatic locking of the matching nozzle – preventing incorrect refuelling with diesel or other media. Protection against confusing diesel and AdBlue® filler necks, especially in fleet operations.

⬇️

Gravity Kit – refuel without a pump

The PIUSI Gravity Kit (€155) enables the dispensing of AdBlue® by gravity – no power, no pump required. With a 3 m hose (DN 19), a manual nozzle and a foot-valve adapter. For vehicles whose AdBlue® tank stands higher than the storage container, gravity is not suitable – then a pump is needed.

Frequently asked questions about AdBlue® accessories

DN stands for nominal width (Diameter Nominal) – DN 19 means an internal diameter of 19 mm. This is the standard diameter for AdBlue® dispensing hoses on pumps and dispensers with 3/4" and 1" connections. When selecting a hose and connections, the DN and the thread type (BSP, NPT) must match. For higher flow rates over 40 l/min (e.g. truck refuelling), a larger hose (DN 25) is recommended.
200 L steel drums and plastic drums have various threads at the bung opening: 2" BSP (British Standard Pipe) – the most common standard thread. 70×6 – the so-called Mauser thread on certain plastic drums. 56×4 – buttress thread on certain plastic drums (e.g. the Mauser type). If unsure: measure the bung thread with a calliper (the external diameter of the thread) or ask the drum manufacturer. PIUSI offers four AF2 variants for all common sizes.
A union nut (ÜWM) is a nut that is screwed over the counterpart – the connection is made from the outside, releasable without tools. A nipple is a spigot with an external thread that is screwed directly into an internal thread – a firm connection, requiring a tool to release. On pumps and dispensers, the outlet connection is often designed as an internal thread (IG) or external thread (AG) – select the matching hose-connection model accordingly. If in doubt, check the pump's product data sheet.
A check valve on the suction hose prevents the liquid from flowing back and emptying the suction line when the pump is switched off. Without a check valve, the pump has to refill the suction line at every start (the priming process), which costs time and can cause problems with self-priming pumps. With a check valve, the line stays filled and the pump starts immediately at full flow. Particularly useful with longer suction lines and pumps without dry-run protection.
PIUSI accessories use standard threads (1" BSP, 3/4" BSP) and are generally compatible with other pumps, provided the thread size and connection type match. For TECALEMIT HORNET systems: HORN also uses 1" connections and is compatible with PIUSI fittings. Important: always use AdBlue®-resistant materials (PP, PVDF, EPDM, stainless steel) – no standard water fittings made of brass or copper, as these are corroded by AdBlue®.
The PIUSI Gravity Kit (€155) uses gravity to dispense AdBlue® – the storage container stands higher than the vehicle tank, and the AdBlue® flows by itself. Contents: a 3 m hose (DN 19), a manual nozzle and a foot-valve adapter for the tank. Suitable for: stationary placement of the IBC container on a raised platform, small quantities without pump noise, locations without a power connection. Not suitable when the vehicle tank is higher than the storage container or when fast refuelling (over 5–10 l/min) is needed.
