Compatibility and Fitment
This o-ring suits compatible Thermo King compressor applications using X418, X426, X426LS, X430, and X430LS compressors. However, buyers should still compare the removed seal and compressor setup before fitting, because earlier rebuilds can change internal service parts. This part is a suitable replacement for the part numbers and applications shown below. Some changes in installation may be required. 33-1221, 331221
Compliance and Safety
Only fit this o-ring during proper compressor service work, and keep all internal parts and sealing faces clean during reassembly. Also inspect the groove, mating surface, and nearby compressor parts, because damage in those areas can cause repeat leaks even when a new seal is fitted. If the compressor shows broader wear or contamination, a more complete repair may be the better option.
Trailer Applications
Thermo King Suction Screen O-Ring X430 suits refrigerated trailer and transport refrigeration repairs where a matching X430 family compressor needs targeted resealing. It works well during overhaul work, and it also helps workshops address seal-related leakage on compatible units. As a result, fleets and repairers can source a practical replacement for routine compressor service jobs.
