MAN TGA/TGM/TGS/TGX Air Brake Charging & Non Return Valve Assembly 81521106092 Horn Valves & Pulls

Description:
This listing is for a used genuine WABCO air brake charging and non return valve assembly for MAN commercial vehicles. The assembly consists of the WABCO 4341002280 charging / overflow valve (tag number 81.52110-6092) and the WABCO 4340140000 non return valve (tag number 81.52120-6004), linked together on a common union block with plastic air lines, exactly as shown in the photos. These components correspond to MAN OE reference numbers 81521106092 (pressure / charging valve) and 81521206004 (non return valve) and are used in the compressed air brake system to control compressor charging pressure and prevent backflow in the supply circuit.

According to WABCO and MAN application catalogues, this valve combination is fitted across a wide range of MAN trucks including LE, FE, TGL, TGM, F2000, M2000, TGA, TGS and TGX models, in various Euro 3–Euro 5 configurations. Cross references include DAF 1517986, Iveco 04675914, Scania 1308510 / 1932747, Neoplan 81521106092 and several PACCAR and Renault / Iveco / MAN references for the non return valve section. Please confirm the part numbers 81.52110-6092 / 81.52120-6004 or MAN 81521106092 / 81521206004 against your existing unit or VIN-based parts catalogue before ordering, as there are multiple similar valves in the MAN air system range.

The unit was removed from a running vehicle and the air brake system was checked for correct build-up and holding of pressure before dismantling, so the assembly was tested on the truck and found operational at the time of removal. Condition is used, grade B: cosmetically it shows typical working wear, dirt and some surface corrosion on fixings and housings, but no visible cracks or other structural damage to the valve bodies. All ports and threads appear intact. Rubber hoses are supplied mainly for reference to orientation and may be reused at the buyer’s discretion, but we recommend new hoses, seals and O-rings during installation.

Professional installation by a workshop familiar with air brake systems is strongly recommended. After fitting, the air system should be pressure‑tested and checked for leaks and correct cut‑in / cut‑out pressures. No coding or electronic programming is required as this is a purely pneumatic component.

The part is an original WABCO product manufactured in Germany, ensuring OE quality and full compatibility with the MAN air brake layout when the correct reference numbers are matched.
