A fitting used to connect pipes at an angle, often 90 or 45 degrees, characterized by having one end with male threads and the other with female threads is frequently encountered in plumbing and piping systems. This configuration allows for direct connection to another fitting or pipe without requiring an additional coupling.
The utilization of these fittings streamlines installations by reducing the number of components required, thereby saving time and minimizing potential leak points. Their design is especially advantageous in confined spaces where traditional elbows with female threads on both ends would necessitate an intermediate nipple. Their availability has contributed to more compact and efficient plumbing layouts over time.
