Gauge, Air Relief Assy. (r0357200)
I'm looking for the O ring on the R0357200. The small one that is in the relief valve that unscrews to release air pressure at the back.
Hi. Wayne. Unfortunately, that o-ring only is not available. You will have to replace the Air Relief Assy. - R0357200.
Less than 1 hr
1. Unscrew assembly from the filter housing
2. Screw in new assembly.
I was just going to replace the gauge but when I tried to unscrew the assembly the thread stem snapped, so it forced me to replace the whole unit.
(4 out of 5 stars)

My first one was 12 years old and unreadable. When I went to unscrew it from the filter housing the threaded stem snapped so I just replaced the whole unit with this. It was easy to install, doesn't leak and works great. Would have given it 5 stars except for it is a little pricey for what it is.
