Original LESER spare parts are the guarantee that also after maintenance works your safety valve precisely fulfills its task to protect people and environment. Learn with the spare pare finder which subassemblies are installed in your individual safety valve to be able to order the correct LESER spare part. The spare part finder shows the bill of materials of your individually configured valve.

The list shown contains all components, regardless of whether they are needed as spare parts. As initial spare parts supply for API, High Efficiency, High Performance, Compact Performance and Modulate Action safety relief valves, we recommend the Spare Part Kits. For the other product groups please contact us for an initial spare part offer. Find out more about LESER Spare Parts Kits.

Please enter a combination of a serial number and an article number to bring up the right spare parts (e.g. Ser-No: 10202021, Art-No: 4411.4443). You can find the serial and article numbers on the name plate of the valve or on the Certificate for Global Application, which you can download in the CERTIFICATES-area.

Some items in the bill of materials are subassemblies which contain one or more of the following items. In most cases the subassembly should be ordered as a spare part.
