FlowTite PEX 4-All push-fit supply stop valves from ACCOR Technology install on new PEX pipes without tools, soldering or gluing. The design incorporates two stainless steel, dual-gripper rings for an increased margin of safety, eliminating the need for an insert fitting due to variations in the outside diameter. The valves are tested to 1,000 psi, are lead-free and come with factory-attached connectors to help eliminate joint leaks. They are available in three colors — clean white, brushed chrome and oil-rubbed bronze ­— at wholesale outlets. 800/447-5848; www.accortechnology.com.
