The present disclosure provides a wing nut including an arcuate body, an arcuate insert, a retaining ring, and a support member. The arcuate body defines a first portion of a mounting thread and the arcuate insert defines a second portion of a mounting thread. The arcuate insert and the arcuate body are complementary to one another such that when connected, the arcuate insert and the arcuate body define an upper ring and a collar and the first and second portions of the mounting thread define a complete mounting thread for receiving a threaded male pipe end. The retaining ring is for securing the collar, and the support member is for securing the upper ring. The wing nut is designed to replace an existing wing nut on a hammer union connection that has deformed lugs. The wing nut can be safely replaced in the field without any special equipment or training. |
