Marketing InformationMade by the original manufacturer of blue Glue, Weld-On® 750™ HotWeld™ PVC solvent cement produces strong, reliable pipe joints in wet environments. This PVC pipe cement creates a deep fusion between rigid SCH 40 pipes and fittings with an interference fit up to a 6 in Dia and SCH 80 pipes and fittings up to a 4 in Dia. The premium, hot blue formulation is designed specifically for irrigation, DWV (drain, waste and vent), pool and spa, plumbing and non-pressure applications. And thanks to its medium bodied viscosity and fast relative set time, this PVC solvent cement applies smoothly and sets quickly to facilitate efficient PVC welding, even in wet conditions. HotWeld™ may be used without primer on SCH 40 pipes and fittings if local code permits.
