Designed specifically for pool repair and servicing, Weld-On 13344 Pool Fast 748 Blue PVC Solvent Cement .5 pt excels in wet environments to create strong and reliable bonds. Compatible with pipes and fittings with interference fits up to 6 inches in diameter (and up to 4 inches for Schedule 80), this solvent cement has an ultra-fast setting time that allows pipes to be pressurized quickly, making it an ideal choice for pool service businesses. The medium-bodied PVC cement applies smoothly and can be used without primer on non-pressure systems if local codes permit. The solvent goes onto pipes with a blue color and fades to clear in sunlight.
