Spiral Tubes
Description
Earth Composites’ Spiral Tubes are high-performance HDPE spiral flow tubes designed for efficient vacuum infusion, vacuum bagging, RTM, VARTM, and advanced composite manufacturing processes. Engineered with a precision spiral structure, they provide consistent resin distribution and effective vacuum evacuation across complex laminate geometries. Manufactured from premium high-density polyethylene (HDPE), these tubes offer excellent flexibility, crush resistance, and chemical compatibility with epoxy, polyester, and vinyl ester resin systems. Ideal for wind energy, aerospace, marine, automotive, railway, and industrial composite applications requiring reliable resin flow and optimized infusion performance.
