Hi everyone,
I have two drain valves leaking by the left front tire that appear to be leaking from the knob and not the threaded connection
The air schematic says the lines are 1/4" .
It looks like the top where the line goes in is a push pull connection but im not sure of the number of other pieces I will need to make the repair.
If anyone has the part numbers and or proper names of the parts I need to replace I would appreciate it.
We are currently on the road and don't want to take things apart and be stuck.
Thanks
Frank
On my 2003 U320 those are turn knobs. I had one leaking while I was at Camp Foretravel. FOT parts has them.
I changed it myself in the parking lot. Don't know the correct descriptor nor part number.
No need to disturb the air lines, the turn valve unscrew. 2 wrenches, one for turn valve, one to hold fitting it screws into.
Those look.like may be original so it Will likely take some force. I would replace all 4
3 in the front, one in the rear
Frank,
You have a 1/4" hose coming into a bulkhead fitting with a hose fitting on one side and 1/4" FM fitting on the other. ( don't look like that needs replacing) You will need to take an open-ended wrench and hold the side of the fitting below the angle mounting bracket. Get another wrench and use it on the valve to remove it. Most any 1/4" valve with male threads on one end or use a standard valve and use a nipple to connect will work. Most any hardware store will have a better quality valve than the ones you have.

Thanks Dan & Mike
Mike not sure
"or use a standard valve and use a nipple to connect will work."
Will see what I find tomorrow or after the holiday.
Frank,
On our coach those valves have male threads on one end. A standard valve will have female threads on both ends. If those little valves are like ours you will need some short 1/4" nipples to be able to screw the new valve into place. On ours we used 2 different length nipples to be able to get the handles to pass when screwing together. I used 2 close (this is as short of nipple made) nipples on the outside valves and one nipple about 2" long on the center valve.

These valves are good quality and dont need the nipple. Ive had good service with them. Added bonus if you ever have to be towed the driver can thread his hose into the outlet side without disturbing your air lines and open the valve.
