Volvo/Renault C/K/T Air Tank 15L 21187782 7421187782 BP0751677 15bar Euro 6 Used Air Tanks

Description:
This listing is for a genuine-type Frauenthal Automotive compressed air tank, OEM type 21187782, commonly used by Volvo Trucks and Renault Trucks. On Volvo applications it is listed as air tank 15L 21187782 for FH series, and on Renault Trucks it cross-refers to 7421187782 for C, K and T range tractors and rigids (Euro 6). The tank is a welded steel cylindrical reservoir with multiple ports for connection into the vehicle compressed air system.

Technical specification (typical for 21187782 / 7421187782 tanks): capacity 15.0 litres, working pressure up to 15.0 bar, operating temperature range −50 °C to +100 °C (as printed on the label), built to EN286‑2:1992 standard. Approximate dimensions are 385 mm overall length and 246 mm outside diameter, with M22 x 1.5 main threaded ports and multiple auxiliary connectors to suit OEM pipework. Net weight is around 5.8 kg. These parameters match aftermarket equivalents such as DT Spare Parts 2.44349 and Febi Bilstein 199267, confirmed as replacements for Volvo 21187782 and Renault Trucks 7421187782.

The tank is chassis-mounted on the vehicle, usually at the rear or along the frame rail, and is part of the compressed-air system supplying service brakes, parking brakes and air suspension. It is suitable for Euro 6 vehicles operating with 24V electrical systems, but the tank itself is a purely mechanical pressure vessel with no electrical components.

Compatibility:
Based on OEM and aftermarket catalogues, this air reservoir is compatible with:
• Volvo FH series (Euro 6) using OEM air tank 21187782.
• Renault Trucks C series (2.3 m and 2.5 m cab), K series construction trucks and T series long-haul tractors, approximately 2013–2021, where OEM 7421187782 / 21187782 is specified.
Always cross-check your existing part number (21187782 or 7421187782) and dimensions before purchase. The tank may also interchange with quality aftermarket references DT 2.44349, DT BP0751677, Febi 199267 and equivalent 15L 15 bar reservoirs.

Condition:
Item Condition — Used original Frauenthal Automotive air tank, type 21187782, 15L 15 bar. The label shows production year 2014. The tank was removed from a running vehicle and the air system was checked for proper pressure build-up and no leaks before dismantling. Externally the tank has been repainted in grey and shows cosmetic wear, including surface rust spots, scratches and marks from brackets and road debris. No structural damage, bulging or weld repairs are visible on the shell or end caps. Threads on ports look serviceable; included brass connectors and plugs come as shown but are considered consumables and may need to be changed during installation. Internally the tank has not been blast-cleaned, so some normal internal corrosion may be present, as expected on a used air reservoir.

Installation notes:
This part should be installed by a qualified technician, following Volvo or Renault Trucks workshop procedures. After installation, the full compressed-air system must be leak-tested and drained to remove moisture. In most cases no programming or electronic calibration is required because the tank is a passive mechanical component, but ensure all safety valves and pressure sensors in the circuit operate correctly after replacement.
