Product Overview
The HOME-FLEX 18-406-020 is a 2-inch IPS 90-degree elbow for changing direction in a compatible underground yellow polyethylene fuel-gas piping system. Its two equal-size mechanical connections allow an approved 2-inch IPS pipe run to turn through a right angle without introducing a threaded metal connection at the bend. The fitting is supplied ready for system assembly with an internal stiffener for each connected pipe end.
This elbow is part of the HOME-FLEX Underground system and is intended only for direct-burial applications using approved IPS yellow MDPE or polyethylene gas pipe carrying natural gas or propane. It is not compatible with HOME-FLEX CSST, and the two product systems must not be mixed. HOME-FLEX lists this mechanical fitting family under ASTM F1924 Category 1. A 2-inch system component is generally used only where the engineered flow requirement and local approval support that size. Include the elbow’s fitting adjustment value in the developed-length calculation and verify pipe SDR, gas pressure, connected demand, routing, trench requirements, tracer wire, testing, and inspection from current project documents. Confirm the marked 2-inch IPS pipe size and authority approval before ordering.
