Illuminators & Level Switches

New product development is a priority at Penberthy, and is no better demonstrated than by the new Graph-a-Bond™ gasket and XP Illuminator. The Graph-a-Bond™ is a patent-pending graphite composite gasket that provides both superior strength to resist gasket deformation and better surface adhesion than commonly used graphite gaskets. The XP Illuminator is the first standard lamp illuminator with a watertight seal. This provides flat glass gage illumination outdoors with a product that's impervious to the elements and can operate maintenance free and reliably for years.
