14mm - 150mm Blanking Rubber Grommets Closed Blind Grommet Plugs Bung Black

Introduction

 
These black closed blind rubber bungs are manufactured from high-quality natural rubber and EPDM rubber, covering mounting hole sizes ranging from 14 mm up to 150 mm with about 1 mm allowable dimensional tolerance. Designed as fully blanked closed grommet plugs without central through-hole, they serve as professional sealing and insulating caps for unused wiring outlet holes on all kinds of electrical enclosures. They work reliably under ambient temperatures between 0°C and 60°C, perfectly blocking empty cutouts to prevent dust, moisture and foreign debris from entering cabinet interiors while shielding internal wiring against sharp metal edges and mechanical abrasion. With full-size options available and straightforward installation process, these blind rubber plugs become essential auxiliary fittings for low & high voltage electrical projects and daily equipment maintenance.
