Plumbing Union Elbow 1/2

The Smith-Cooper 4318000050 is a 90-degree union elbow designed for 1/2-inch pipe connections. It carries a 300-gallon rating suitable for standard plumbing installations. The fitting is supplied new and was first listed by the manufacturer in 2022.

Replaces Worn Or Damaged Fittings

This elbow replaces a leaking or corroded union joint without requiring a full pipe replacement. The jump is worth it when the existing fitting shows seepage at the threads or the union nut no longer seals. A new union restores a reliable, removable connection point.

Threaded Union For Straightforward Assembly

The union design allows the two halves to be tightened by hand and finished with a wrench. What usually goes wrong is cross-threading the nut or over-tightening, which can crack the fitting body. Clean threads and proper sealant prevent most installation issues.
