Infusion spiral is a spiral wound plastic tube which allows very easy flow or resin from the resin feed tube into and around a resin infusion project. Infusion spiral is typically positioned underneath the feed line directing resin flow into the further corners of the part.
Like most other elements of the resin infusion process, the spiral infusion tube cannot be reused once resin has flown through it and therefore should be considered a disposable consumable of the process.
