Features

COST-EFFECTIVE AND EFFICIENT
Lighter weight can mean faster installations—helping save time, labor, and money.

LONGER LIFECYCLE
Our PVC offers virtually corrosion-proof, impact-resistant performance.

SAFER TO HANDLE
The low-VOC (486 and 508 grams/litre for the 1 Step and 2 Step products respectively) solvent cement application eliminates the need for—and risks associated with—specialized tools, like torches. 

INCREDIBLY VERSATILE
Can be used for both above and below grade applications with pipe and fittings available in 1.5- to 10-inch diameters and pipe in 12-foot lengths.
