Seals


Gland Packing





Gland Packing acts as a protective sleeve over a cable or for piping in applications where pressure or other factors pose as a threat.


Gland packing is often used instead of a mechanical seal as packing is cost effective, easy to install and can be used in various types of products.

-  VALVES

-  PUMPS

-  BOILERS


INDUSTRIES WHERE PACKING ARE USED:

-  FOOD

-  MINING

-  CONSTRUCTION

-  METAL INDUSTRY

-  FARMING
