Expander Plugs Series Sk 552 Long Mandrel

Pull-style expander seals use an integrated mandrel to insert the expander plug into a drilled hole. The KOENIG EXPANDER® SK 552 Long Mandrel plug does not require the hole to be counter-bored, and is often used for angled channels or installations with difficult orientations. They are ideal for installations with space or weight constraints.
