Volvo FH/FM Air Tank 21187789 7421187789 2.44338 1051719/0082 25L 15 Bar Euro 6 Air Tanks

Description:
This listing is for a genuine Frauenthal Automotive compressed air tank, type 21187789, as used on modern Volvo and Renault heavy trucks. It is a 25.0 litre steel air reservoir designed for use in the vehicle compressed-air and braking system. The label specifies EN286-2:1992 compliance, working pressure 15.0 bar, temperature range –50 °C to +100 °C and manufacturer code FHU 1051719/0082, with year of manufacture 2014. The tank has four M22 x 1.5 threaded ports for connection to the air system and drain valve.

According to Volvo and Renault cross-reference data, OE number 21187789 is fitted to Volvo FH, FM and FMX Euro 6 series trucks (from around 2012/2013 onward) and to Renault Trucks C, K and T models of similar generation, where it serves as a chassis-mounted air reservoir for the service and parking brake circuits and auxiliary air consumers. It crosses to Renault reference 7421187789 and aftermarket replacements such as DT Spare Parts 2.44338, which confirm the 25L capacity, approx. length 501 mm, outer diameter 276 mm, working pressure 15 bar and M22 x 1.5 port threads.

The part offered here is a used original Frauenthal tank removed from a running vehicle. Before dismantling, the truck’s air system was charged and checked for correct pressure build-up and leak-free operation. After removal the reservoir was visually inspected and pressure-held; no leaks, structural dents or weld failures were found. Cosmetically the paint shows normal wear, scratches, mounting strap marks and some local surface rust staining, but no perforation. The identification label remains readable, showing type 21187789 and EN286-2:1992. Threads on all ports are intact; existing fittings and drain valve are left in place as shown for the buyer’s convenience.

This tank is suitable as a direct replacement on compatible Volvo FH/FM/FMX Euro 6 and Renault C/K/T chassis that were originally equipped with OE reference 21187789 / 7421187789. For safety reasons, always confirm compatibility with your VIN and parts catalogue before ordering, and ensure that installation is carried out by a competent workshop. The air system must be depressurised before removal, new sealing rings or thread sealant used on connections, and the tank mounted with correct brackets and strap torque. After installation the complete compressed-air system should be leak-tested and drained of condensate according to manufacturer maintenance schedules.

The item is supplied as pictured: one used Frauenthal 25L steel air tank with existing ports and drain valve. No additional brackets, lines or sensors are included. This is an ideal cost-effective OE replacement for a corroded or damaged original reservoir on a Euro 6 commercial vehicle.
