Reactor Vessel Stud Hole Plugs

The Master-Lee Engineered Products Reactor Vessel Stud Hole Plugs provide an effective and reliable seal to prevent water or debris from entering the vessel stud hole during refueling maintenance outages.

Made from a nylon body, stainless steel top plate, and molded neoprene gasket the lightweight plug is very durable and easily cleaned.

The Reactor Vessel Stud Hole Plugs are installed using our T-Handle Tool. With the tool’s ‘easy-align’ connector, the plugs are quickly and easily installed or removed.

The threaded portion of the nylon body precludes galling due to thermal expansion and also prevents damage to the stud hole threads of the vessel.

The stud hole plugs are shipped and stored in a DOT Type 7A container. Partitioned crate compartments ensure minimal contact with the plugs’ threads ensuring years of service.
