1/2" brass sprinkler extension
Based on the specs in the description of the product, I had thought I was receiving a 1/2" X 1/2" extension that was 0.62" in length. When I received the fitting it was 1" in length. Although I was able to make this work with some minor modifications, the 0.62" inch fitting would have worked perfectly.
