The Z-Flex Z-Vent 2SVEEWC0390 3-inch single-wall 90-degree gas vent elbow is precision-engineered to redirect combustion exhaust lines within high-efficiency mechanical layouts. Constructed by Flexmaster Canada using AL29-4C superferritic stainless steel, this robust fitting provides supreme chemical resistance against the corrosive acidic moisture frequently generated by condensing heating appliances.
Equipped with a built-in, fail-safe double lip gasket connection system, this single-wall elbow creates a highly reliable gas-tight and liquid-tight seal without needing external sealants or curing periods. This self-sealing layout dramatically accelerates the overall assembly workflow for mechanical contractors on the job site while effectively protecting against toxic flue gas bypass or fluid leaks.
This 3-inch 90-degree elbow is approved for high-performance Category I, II, III, and IV venting layouts, making it highly versatile for various installations. Whether routing through horizontal termination points or complex vertical shafts, it fits securely with compatible tankless water heaters, condensing wall boilers, and modern space heaters, ensuring robust compliance and system safety.
