Lead Wool, a form of caulking Lead, is long, fine strands of
chemical grade Lead which is twisted into 5/8”rope for use in
various applications and is available in 5 lb. cartons or 50 lb.
waterproof bags. It averages about 2-½ ft. to one pound. Lead wool
is certified to meet Federal Specification QQ-C-40.
The Lead Wool is used to seal flanged connections, cast iron,
cement and earthenware pipes, and apertures of walls and ceilings.
Very good ductility of Lead ensures fast and easy filling and
sealing of small slots too. It is also convenient for anti-radiation
protection. The Lead resistance to aggressive environment is a
warranty of long-term durability of seal.
Lead wool is made by scratching fine strands from the surface of
a Lead disc. It is used for the caulking of joints in large pipes
e.g. gas mains and in some specialist batteries.
