Bouchon gris pour collecteur De Dietrich 7844703

A grey cap for manifold is a small but important accessory that helps protect unused ports on your heating manifold from dust, debris, and accidental leaks. These caps are typically used to seal off outlets that are not connected to a circuit, maintaining system integrity and preventing contamination. Made from durable plastic, the grey cap is easy to install and provides a snug fit on standard manifold connections. Keeping spare caps on hand is a good practice for any heating engineer or homeowner performing maintenance, as they help ensure the manifold remains clean and functional.
