PVC schedule 40 NSF listed fitting from 1/2" through 6". Unlike metal, PVC fittings never rust, scale, or pit, and will provide many years of maintenance-free service. PVC can handle fluids at temperatures up to 140°F, allowing a wide range of process applications. Lower material costs, lighter weight and ease of installation, can reduce installation costs by as much as 60% over conventional metal systems. Smooth interior walls result in lower pressure loss and higher volume than conventional metal fittings. PVC Valve products are available for total system compatibility and uniformity; NOT FOR USE WITH COMPRESSED AIR OR GAS
