Chesterton 442C splitseal
A “high performance” split mechanical seal for universal application.
The 442 seal is the world’s most popular divisible seal, available in an endless series of shaft sizes from 38 to 900 mm. The 442 C successor to the 442 split seal is a development of the 442 seal. The seal is even more compact, even easier to assemble and resistant to higher loads. The versions in terms of running surfaces and o-rings have also been expanded. The 442C seal is a combination of a split seal with cartridge seal properties. The treads are pre-assembled in the shared sealgland. The treads, o-rings and springs are automatically put in place during assembly and applied to the correct pressure. It goes without saying that these new and unique technical details are patented.
