PVC Schedule 40 pipe and fittings exhibit consistent quality with uniform properties. GF Harvel uses its own custom blends of PVC compounds to offer you two pipe brand choices to ensure that desirable physical properties are maintained for various applications. GF Harvel’s Industrial PLUS brand exhibits exceptional quality you’ve come to expect from GF Harvel, including CSA (Canadian Standards Association) B137.3 approval and uniform physical properties; making it the preferred choice of fabricators and custom houses. For customers who do not require CSA or fabrication grade pipe, you can choose to use our Industrial brand. Schedule 40 PVC is white in color and the pipes have the largest inner diameter of the three schedules.
