Will this seal work for a fluidmaster 300? I don't seem to be able to find any information on this series?

Asked by Cuando October 4, 2016

Yes as posted by Fluidmaster support this will work 300 Fluidmaster model. I purchased 2 from my local home depot today. I easily removed the old washer and installed the 242. The squeaks, noises constant running of tank issue are all gone. See my pictures the wet one is the old damaged one and new one is on left. They are identical in size and appearance. Per Fluidmaster support: The 242 seal is used in all of our fill valves including the 300 model, that means that you can use it to try to fix your issue. If after replacing the seal you still have the same problem then the recommendation would be to remove (completely) the 300 valve from the tank and get the model 400A which is the direct replacement.

How do you know if the seal needs replacing...how should it look or Not look

As the seal deteriorates it changes color and texture. This prevents it from sealing properly and the water leaks slowly at first before it becomes more constant. You can test this by turning the water valve off once the tank is full. Hours later your tank will either still be full or it will be empty.

How do you know if you need to replace the seal vs. the cap vs. both?

It's usually the seal that gets worn out over time.

Asked by PhillDL July 11, 2018

Probably. If you push the float down an inch or so (after the tank has filled) and let it pop back up, and the leakage stops, then the old seal is probably not shutting off the flow of water when the float slowly comes up. In this case ( which is what my valve was doing) a new seal should fix the problem.

I know it worked for me. It was worth a $2 investment when I needed to fix my toilet. It was try this seal or replace the entire unit ($25-30), the seal was my answer.

after you remve the cap, you must also remove the plastic retainer. It has two tabs that you must pry up slightly, then turn the retainer CCW. The seal is under the retainer.

will this seal fit

Yes, this fits the fluidmaster 400A, the mansfield isn't a flush valve it's the tower or flapper like thing. I had a friend who had a $700 Kohler toilet that kept running, he didn't know the fill valve was a fluidmaster(it looked completely different then the 400a model) but when I took it apart it was the same washer inside. I have a feeling this is used in the entire line of products.

Functions perfectly in the FluidMaster 703a series fill valve in my Glacier Bay toilet. Sadly, the rubber doesn't do well with my water, so I have to replace it every year or so. Luckily, it's a lot cheaper than replacing the whole fill valve. I tried coating it in silicone grease, hopefully it helps it last a little longer.

Excellent. Fixed slow fill on our dual flush toilet in less than 5 min. Lots of videos on internet to help diagnose problem with duel flush and replacement, may require a #2 Phillips screwdriver. Keep a spare as this problem reoccures about annually.

Instructions on product packaging were clear and easy to follow. Switching out the seal only took a few minutes (10 to 12 minutes), including flushing fill valve prior to replacing the old seal and testing the new seal after replacement. I appreciate the manufacturer providing this option for fill valve repair. Prior to learning about these replacement seals I would have replaced the whole fill valve assembly. The seal replacement saves a lot of repair time, and saves customers a substantial amount of money per replacement.
