The adjustable muffler is for the ED7021 gate valve. If it gets clogged it will quit exhausting air causing the lift gate to act up. It's adjustable and exhausts the air pressure from the system out to allow the lift door to lower back down to be locked.
When needed, the speed of the tool that utilizes the adjustable muffler may be decreased or increased with the adjusting bolt. The final position is then locked in place by the lock nut. If your trailer needs a new adjustable muffler, order this part today.
