Do Teflon seals require lubrication?
Slippery: It’s not just water, oil, and dirt repellent – it repels everything! (PTFE is so slippery that insects cannot get a grip, and tend to fall off.) This feature is beneficial in a number of sealing applications across industries, because it means the seal does not require lubrication.
How do PTFE seals fit?
Position the assembly sleeve with the PTFE oil seal on the shaft. Make sure that the sealing ring is aligned correctly – the sleeve must be located so that the seal can be pushed onto the shaft smoothly. Push the sealing ring onto the shaft with an even motion.
How do you press oil seal without damaging it?
