Graphite PTFE Shaft Seal

Product Code: S4050
Definition : Graphite PTFE yarn is of high quality and homogeneous material improved PTFE resin through a graphite powder process. It has a low friction coefficient and thermal conductivity. Chemicals used in most environments.

This packing is braided from PTFE graphite yarn. Its high thermal conductivity is especially committed to provide an effective seal at high temperatures and speeds. The graphite particles to the surface in the free state not causing little contamination.

Sulphur Quality shaft seal PTFE Graphite :
PTFE graphite is woven from yarn.

Oily Graphite PTFE shaft seal :
Silicone lubricants are woven from yarns of graphite.

Applications : The piston and gear pumps, are commonly used on valves. Especially high speed and give better results than pure PTFE seal in a hot environment.
