The 90 Degree Medium Spigot Elbow has a male and female end which enable you to connect one fitting or elbow directly to another to create a 90 degree turn. This allows for more flexibility in order to avoid beams or other obstructions when creating pipe runs and also ensures proper air flow.
The 90 Degree Medium Spigot Elbow is used in place of a 90 Degree Sweep Spigot when a tighter turn is required, but its use should be minimized in order to optimize performance.
