A Step-by-Step Guide on Repairing the Therm-a-Rest WingLock™ Valve


If you own a Therm-a-Rest sleeping pad with a WingLock™ Valve, you’re probably familiar with its convenience and durability. However, even the best-made products can experience wear and tear over time. This article will guide you through repairing the WingLock™ Valve, ensuring your pad remains used for many future adventures.

Identify the Damaged Valve and Remove it from the Pad

  1. Examine your sleeping pad and identify the damaged WingLock™ Valve. Look for any signs of leakage or difficulty in inflating and deflating the pad.
  2. To begin the repair process, you must remove the damaged valve from the pad. Locate the small tab on the valve base and pull it upwards to open the valve wings.
  3. Once the valve wings are open, grab hold of them and the valve itself and gently pull them away from the pad. Apply consistent force to remove the valve, but be careful not to damage the pad.

Install a New Valve by Cleaning the Valve Seat and Lubricating the O-ring

  1. Now that you have successfully removed the old valve, it’s time to install a new one. Clean the valve seat on the pad using a soft cloth or tissue.
  2. Take the new valve and apply a small amount of lubricant to the O-ring. This will ensure a smooth and airtight fit.
  3. Align the new valve with the valve seat on the pad and push it in, using a twisting motion, until it is fully seated. Ensure that the wings are closed while doing so.


Test the Repair and Prepare for Your Next Adventure

  1. To test the repair, inflate the pad fully and leave it overnight. Check for any air pressure loss to ensure the new valve is secure and airtight.
  2. If the pad maintains its inflation without issues, congratulations! You are now ready for your next outdoor adventure, knowing your sleeping pad is in excellent condition.
  3. If you encounter any problems, repeat the repair process or contact Therm-a-Rest customer support for further assistance.
