KOENIG EXPANDER® SERIES LK 950 – OVERVIEW

pull type expander seal
SERIES LK 950 Expander Plug

Pull-style expander seals use an integrated mandrel to insert the expander plug into a drilled hole. This type of KOENIG EXPANDER® Series LK 950 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. If you are unsure if the LK 950 expander sealing plug series is the right component for your application, use our Product Selector to identify the best KOENIG EXPANDER part for your specifications.
