Product details
Lead wool consists of thin strands of lead and is primarily used as caulking to seal joints between lead and steel fittings but is also used in certain gas detection systems where the purity and quality of the wool is critical.
Supplied in a range of lead alloy specifications from 0.5% Antimony to high-purity lead, the specification of lead wool is dependent on the application.
Calder is the only UK manufacturer of lead wool. Our production process is entirely in-house at our Chester site.
