The glass fitter is a must when using the Water Filtration Whip with a water pipe that has a glass stem larger than 14mm. This will allow your connection to be smooth and with the ground glass there will be no vapor to escape. The ground glass ensures a leak-proof connection and is necessary when using the water pipe wipe.
Weighs 10 grams and is 1 ¼” in length. Ground glass connection to fit 18mm downstems.
