Riding against a moving shaft or rod, this seal keeps lubricant or hydraulic fluid in and grit, water, and contamination out, so the surfaces it protects run clean and the system holds pressure. The flexible lip wears with use, and once it hardens or cracks, fluid weeps past it and contamination can reach the parts it guarded. A weeping or dried-out seal is the signal to replace it.
Riding against a moving shaft or rod, a seal keeps lubricant or hydraulic fluid in and keeps grit, water, and contamination out, so the surfaces it protects run clean and the system holds pressure. The flexible lip that does this work wears with use, and once it hardens or cracks, fluid weeps past it and contamination can reach the parts it guarded.
A weeping or dried-out seal is the signal to replace it before the leak grows or dirt scores the shaft. Match the inside and outside diameter and the thickness to the seal being replaced, since a seal has to fit its bore and its shaft closely to seal at all.
