TG and TC oil seals may share similar outlines, but in real use they are not simply swap‑and‑go. At DEDE SEAL, we often describe the difference as two seals that “feel” the machine in different ways.

Oil seal performance has changed under new‑energy conditions, mainly because the environment around the seal feels different from traditional machinery. At DEDE SEAL, we often describe it as the seal entering a new rhythm—one shaped by faster speeds,

Chemical compatibility has become a key factor in sealing reliability because a seal spends its entire life touching the fluid it is meant to contain. At DEDE SEAL, we often explain it this way: a seal works best when the fluid feels “comfortable”

It can be surprising to install a new oil seal and notice leakage again, but the cause is often related to the machine’s condition rather than the seal itself. At DEDE SEAL, we describe it as a mismatch between the seal and the environment it’s

It is common to see an O-ring perform well in one machine but experience leakage in another, even when the size and material appear identical. In many cases, the difference lies in the operating pressure rather than the O-ring itself.

When equipment experiences premature oil seal wear, friction is often one of the underlying causes. While oil seals are designed to prevent lubricant leakage, they must also operate continuously against a rotating shaft. Managing friction
