Pullplugs

Pullplugs - Overview

EIS Pullplugs are engineered to provide a secure, permanent sealing solution for drilled and cast holes in fluid power and other precision applications. Their mechanically installed design supports efficient assembly while eliminating the need for threaded holes and additional sealing components. Proper plug selection should consider application-specific factors including hole dimensions and tolerances, housing material, operating pressure, and installation requirements. EIS provides technical specifications and engineering guidance to support proper Pullplug selection and integration.

  • Patent: 10.040,182 available in stainless steel, steel, and aluminum materials.
  • Quickly installs into any depth in as drilled holes.
  • Many sizes & materials are available.
