White plastic plug De Dietrich 7822993

A white plastic plug is a simple yet essential spare part used to seal unused openings in boiler and burner components. It prevents leaks, dust ingress, and pressure loss in systems such as air intake manifolds, condensate drains, or sensor ports. Made from durable plastic, it is easy to install and provides a secure fit. This plug is commonly used during maintenance or when reconfiguring heating equipment. Keep a few on hand for quick repairs or to cap off ports during system modifications.
