Philmac pipe fittings are a top choice for connecting MDPE (Medium Density Polyethylene) pipe, particularly in cold water systems. Their signature 3G Metric/Imperial compression fittings feature “Slide & Tighten™” technology, enabling quick, secure, and leak-proof connections without special tools or pipe preparation. These pre-assembled fittings, made from durable, corrosion-resistant thermoplastics, simplify installation, even in challenging conditions. For metric MDPE pipe sizes, a liner or insert is essential for WRAS compliance and a reliable seal, especially for potable water applications.
