The braided polymer fibers of the BrassCraft Speedi Plumb Plus Push Connect Water Heater Connectors bend freely without kinking, crimping or flattening, making installation easier, especially in cramped quarters. The braided jacket is designed to resist corrosion from most harsh household chemicals that can corrode and deteriorate stainless steel braiding. Polymer fibers are resistant to higher temperatures, which makes them ideal for water heater connections. They have superior corrosion resistance inside and out, and no dielectric union is needed, as it is integrated into the connector, eliminating the need to install a separate dielectric union. A pre-inserted tube stiffener self-aligns with the tubing, creating an installation-ready water connector that creates a durable, watertight seal. It is compatible with copper, PEX and CPVC, and no soldering or glue is required for installation. 877/272-7755; www.brasscraft.com.
