The plastic PEX Press system by Viega.
Viega has introduced the plastic PEX Press system, including Viega’s Smart Connect feature, for joining cross-linked polyethylene (PEX) tubing. The Viega PEX Press system is suitable for potable water and radiant applications in light commercial projects. These fittings feature excellent corrosion resistance and compliance with Zero Lead requirements, as well as NSF approval. Viega’s Smart Connect feature enables installers to easily spot unpressed connections during pressure testing by allowing water to flow past the fitting on a missed connection. The system uses the same hand and power tools as the bronze PEX Press system to join PEX tubing using plastic fittings without O-rings, glues, cements, or lubricants. The hand tools do not require calibration. Viega PEX Press fittings are factory assembled with attached stainless steel sleeves with three view holes, which helps installers insert tubing correctly, ensuring proper installation. Color-coded tool locator rings assure proper alignment of the press tool.
