Rhinestones have the following parts to help thread the pipe better:
1. Elbow: Using the elbow can change the direction of the pipe, making it easier to pass through bends and corners.
2. Elbow clamp: This is a clamp that can be fixed on the pipe, which can help you stabilize and control the position of the pipe elbow, making it easier to pass.
3. Elbow conduit: This is a special pipe guiding tool used to guide pipe elbows to the desired location and reduce the resistance when crossing the bend.
