Ash Catchers are cool attachments that fit onto your water pipe which can provide many positive benefits for smokers. The primary purpose of an ashcatcher, also known as a pre-cooler, is to add an additional layer of filtration which takes place before the smoke from your bowl enters the primary diffuser. While using this attachment an increase in smoothness will be noticed while inhaling and exhaling the smoke. At Sky High Smoke Shop you will come across tons of ashcatchers and it is important for you understand which size you’ll be needing. Please note that attachments usually depend on three things for a perfect fit. First you need to know which joint size compatible with your water pipe. There are three standard joint sizes for every rig such as a 10mm, 14mm, and 18mm. Secondly, you must understand the difference between a male & female joint. Last but not least, you must know joint angel of your rig. If your bong has a 45-degree female joint you will need to purchase a 45-degree male ash catcher. If you have any questions regarding sizing please contact us and we will gladly assist you!
