Drain Cap on Cougar 2012 29BHS

My trailer is stored away from my home (about 2 hours) and I made a foolish mistake winterizing last fall. When draining all the tanks I lost one of the caps on the drain hoses.

Without having to grab a cap of the trailer (since it is so far away), was hoping someone one the forum knows what size and pitch thread the cap is on the drain hose under the trailer.

Much appreciated!!
  • Yes, my trailer has 3 of them. The hoses sticking out of the bottom of the trailer.
  • The lines are most likely 1/2" PEX.
    Go to Home Depot or Lowe's and look for PEX caps for 1/2" line. They come in male and female. Probably buy some of each to be safe.
  • That would be1/2" IPT caps and plugs "caps are what is on mine"
