Compatibility and Fitment

This o-ring suits compatible Thermo King compressor applications using X418, X426, X430, X430LS, and X426LS 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. 33-0230, 330230, 33-230, 33230, 33-3691, 333691

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 mating surfaces and nearby compressor components, 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 Throttling Valve O-Ring X430 Compressor 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.
