A 5-pack of 25mm diameter high quality stainless steel pipe screens, specially designed to fit the Vaporite whip.
To install, first remove the medical-grade plastic hosing (soak in hot water if it doesn't come off easily). Shape the edges of a stainless steel screen around the tip of your finger, and insert into the glass chamber at the wide end. Use a bamboo poker up the narrow (hose) end to help guide the screen into place. It's really easy when you get the hang of it!
(Note: with correct use of the Vaporite the screens should seldom need changing. Vaporising creates no tar so the screen inside will stay clean and might only need a very occasional wipe with alcohol. If the screen gets blocked with tar, you may be running the unit too hot and are smoking rather than vaporising. Just letting you know... )
