According to Financial Times, Wolsely, the plumbing and heating products distributor, has warned some customers in the US and Canada that it may have inadvertently sold them asbestos gaskets.

Following two years of internal investigations, the company disclosed the problem regarding these gaskets today. The company expects legal action to result.

The problem with the parts, used as plumbing seals, was disclosed on Tuesday after two years of internal investigations. It is expected to lead to legal action.

Wolseley reported that four customers in the US and Canada found that the supposedly asbestos-free gaskets contained more than 1% asbestos, the threshold at which the products are required to have a label that it contains the dangerous substance.

The company blames the former Canadian supplier, Lortech rubber.

Ian Meakins, Wolseley CEO, says that it plans to sue Lortech. He also mentioned that he expects that several customers will file action against Wolseley.
