Great information! Unfortunately too late. I had to replace my coach air compressors ($1000) due to burnout caused by these seat leaks, I would get another leak a few months later. Always when I was away from the coach for a few months. I finally put an air shut off on the input line. The Plastic hose were just getting brittle with age and would get a hair line crack and break open.

I replace the seat with an all optioned, MINIMIZER seat ($2000) sold at the Peterbilt store nearby. Love the new seat. For anyone that needs a complete original NEWELL seat just like the one in this thread (leaks fixed but still old plastic parts, I have one sitting in my garage in Kirkland WA. Seat is not going back in.
