Pure Carbon an Interbraid multiservice carbon
filament packing for pumps and valves. It is a special
packing with low friction characteristics adapted easily
and quickly into the equipment and requires only
occasional gland adjustments.
Its heat sinking ability makes this packing an ideal
seal in high speed rotary equipment, sealing against
boiler feed water, steam, oils, aromatic aliphatic
solvents, acids and alkalis except fluorine, oleum,
fuming nitric acid and aqua regia.
