Weld-On 10086 705 Gray PVC Solvent Cement 1 gal is specially formulated to handle a variety of rigorous industrial applications. This PVC pipe cement is designed for use with pipes and fittings with an interference fit up to a 6-inch diameter and is suitable for all classes and schedules (including Schedule 80 up to a 4-inch diameter). The industrial-grade clear PVC cement creates a deep fusion between PVC pipes and fittings, making it suitable for irrigation, DWV (drain, waste, and vent) systems, electrical conduit, pool and spa, and plumbing (including PVC foam core pipe). It can be used without primer on non-pressure systems if local codes permit. With its medium-bodied viscosity and fast relative set time, this PVC solvent cement applies smoothly and sets quickly to facilitate efficient PVC welding.
