Norgen step valve leaking

January 12, 2019, 10:48:12 pm

I have a new to me 2002 Foretravel 270.  I was under the coach looking for air leaks and noticed bubbles at the Norgen step valve where the coil (the square part at the bottom held by two small Allen screws) meets the body (sorry forgot to take picture while under there).  Is there an O ring that can be replaced between the two parts, or do I need a new valve?  Thanks in advance.

I'm not sure if your coach has this version of the Norgren valve, but there are rather unique "O" rings used to seal the top and bottom sections to the valve body. Here are a couple of pictures. The "O" rings for top and bottom look to be identical.

I would save the old one and get a new one.. I tried cleaning mine and couldnt get it to work.. if the budget allows just get a new one.. after climbing under the coach 2 or 3 times to test it.. Worth the $80.00 for me.. Use the old one for parts on the next valve.. but I changed both valves while I was under their.

Thats just me.

We just took ours off, took it apart and found it quite simple inside, cleaned all parts and put it back together, and ours works again ok.

I was able to just tighten the Allen screws on mine and stop a leak.

Mine started leaking badly and when I took it apart to clean I found metal inside the manifold so had to replace it.  Had to drill new mounting holes to make it fit and was able to use the existing hoses.
