The Helix Multi-Purpose Kit is probably one of the most original products that Grav ever made. And this little thing is an official replacement mouthpiece for the Helix Multi-Purpose Kit. What’s so original about it? Well, this mouthpiece delivers a swirling action as you inhale, and it also delivers impressive filtration. It’s resilient and robust as it’s made from top-quality borosilicate glass and decorated with Grav’s Helix etched decal. It measures 5 inches in length, perfect for taking on the go with you. The mouthpiece has a 14.5mm female joint and is a perfect replacement or spare part. If you need one, we’ve got you covered!
