Grav 14mm Glass Cleaning Plugs / Airflow Corks

Many people opt to use a spare finger or thumb to plug their water pipe joint while cleaning, usually resulting in smelly fingers and a nasty mess. These Glass Cleaning Plugs from Grav are the perfect tool for a quick assist in your bong cleaning process, working to create an airtight seal in any 14mm female joint. The Grav Glass Cleaning Plugs also double as convenient air corks for blocking the airflow to one side of any water pipe that features two joints. Snag just one to pair with water pipes like the Grav Dual Function Water Pipe, or choose our convenient 7-pack bundle we designed for use with the Grav Menorah Bong!

To use the Grav Cleaning Plugs, simply replace the hole where your bowl piece usually sits with the glass plug and hold it in place while shaking your isopropyl alcohol or other cleaning solution around the interior of the pipe. We highly recommend sterilizing your glass pipes with a mixture of Higher Standards ISO Pure & Higher Standards Salt Rox for a thorough disinfectant and polished finish when rinsed clean.
