Vacuum Tubing Polyethylene

Vacuum Tubing – Polyethylene (Crush-Resistant) – 25 ft & 100 ft Coils

Clear polyethylene vacuum line designed for composite shop use. The tubing is crush-resistant under vacuum for reliable connections between the part/manifold, catch pot, and pump. Smooth interior walls help maintain steady airflow during draw-down and infusion, and the clear body makes it easy to see resin movement and monitor contaminants.
