KOENIG EXPANDER® SERIES LK 600 – OVERVIEW

pull style expander seal
Series LK 600 expander plug

Pull-style expanders use an integrated mandrel to insert the expander plug into a drilled hole. This type of KOENIG EXPANDER® Series Lk 600 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.

Material:

Sleeve: Stainless Steel, Special Oil Film Lubrication    Mandrel: Stainless Steel, Special Oil Film Lubrication
