First time posting so if this in the wrong place forgive me.
I have a Enco 12x36 Lathe. On of the oil seals in the head stock is leaking . The manual doesn't list a part number just the size. It says it is a PD20 x45x10mm oil seal. When I google it all I can find is a TC20x45x10 Oil seal . Does anyone know the difference between a PD and TC oil seal and can i us e the TC?
