PVC welding rod is the matched filler for rigid PVC plumbing, signage substrate, cafe blinds and PVC sheet fabrication. PVC welds cleanly with a like-for-like PVC rod; substituting PE or PP will not bond and leaves a weak seam.Techspan PVC rod is extruded from virgin material for reliable flow and a strong, neat weld bead. It suits sign-makers, plumbers and fabricators working with rigid PVC, and is available in 3 mm, 4 mm and 5 mm round profiles, plus triangular and rectangular profiles for fillet and butt welds, in 50 m repair rolls and 400 m bulk rolls. If you’re not certain your material is PVC, our plastics identification guide walks through the simple tests to confirm it.
