If you want to make sure that you always have spare parts for your vaporizer, then you should get this basic Dynakit for the Vapcap M. This kit is ideal if you would like to have all of the replacement parts that are used with most of the DynaVap devices. Both types of o-rings are included in this kit in case any of them are broken or lost. Additionally, there are also three extra screens that can be used to replace the original ones. However, the screens included in this kit are only compatible with the Vapcap M. The fat mouthpiece in the kit is not a replacement for an original part. However, you can utilize it as a 14mm water tool adapter. The entire kit includes the following: condenser o-rings, high-temperature o-rings, fat mouthpiece, stainless steel CCD, hard-bristle cotton pipe cleaners, green and purple storage tubes, DynaWax, and degummed hemp fiber.
