Product Overview

Weld-On 781 is a professional-grade PVC solvent cement formulated for joining PVC pipe and fittings in pressure and non-pressure systems. It is a clear, low-VOC, medium-bodied adhesive engineered to produce high-strength solvent-welded joints. The compound is suitable for use with all classes and schedules of PVC pipe up to 6 inches in diameter (Schedule 80 up to 4 inches) that require an interference fit. Weld-On 781 provides rapid set and cure times, ensuring reliable field performance in both residential and industrial piping applications. When permitted by local codes, the cement may be used without primer on non-pressure systems.
