The Gas Kit 4 Inch M Seal WC is designed to create a firm seal between a toilet outlet and a compatible 4-inch drainage pipe. Its flexible sealing construction helps minimise water seepage and prevents unpleasant sewer odours from escaping through the connection.

Suitable for new toilet installations and replacement work, this WC gasket is easy to fit and provides stable, long-lasting performance. It is an essential plumbing component for maintaining a clean and properly sealed bathroom drainage system.
