The 33413TB TCM Oil Seal by Freudenberg NOK is a double-lip nitrile oil seal built for dependable oil retention and enhanced contaminant exclusion in larger rotary shaft applications. Designed for a 3.375" shaft and 4.125" housing bore, this TCM/Dichtomatik-style seal delivers reliable performance where keeping lubrication in and debris out is critical—because bigger shafts still rely on a precise seal to do the heavy lifting.
