PTFE + Graphite Packing for Pumps and Valves

The MF 261 packing is made with PTFE of the highest quality added to a high content of encapsulated graphite , with diagonal braid .

Braiding and graphite make it a very flexible and adjustable braid, combining the extraordinary chemical resistance of PTFE with the great capacity of graphite to dissipate heat . </ p>

This gasket can be considered universally applicable except for strong oxidants such as (nitric acid, liquid alkaline materials).

The MF-261 gasket does not harden and due to this quality the shaft can be lubricated during its service life.

Its thermal conductivity is one of the highest among PTFE + Graphite threads.
