PTFE + Aramid Packing
PA7140 White PTFE packing with aramid corners
The corners of the packing are made from aramid (Kevlar) yarns impregnated with PTFE, while the friction faces are made
from pure PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure
PTFE.
Applications:
Designed for high-pressure reciprocating pumps, medium-speed centrifugal pumps and valves. Can be used for general
service vapors, gases, solvents, mild acids, alkalis and most abrasive liquids.
The packings do not cause stain in pulp & paper mills, pharmaceutical, food and sugar industries.
Forms of Supply:
In coils, e.g. 5kgs or 10kgs per coil;
As packing rings (PR7140, PR7150).
