I wish I'd ordered this part first; I got this to repair the flush valve I changed out of one of the Niagra toilets which was slow to fill; but I'd already bought the full flush valve and replaced it, so I put this seal into the original leaking flush valve to serve as a spare. When my father was alive we'd bought a replacement valve but I couldn't find where we put it...but fortunately Home Depot now carries the valve (don't think they did back 15 years when he had the toilets put in) so having a spare isn't as important, but I'm glad these are becoming more common.

Can a fluid master pro 22 fill valve seal be used on a fluid master 300

Can a fluid master pro 22 fill valve seal be used on a fluid master 300
Asked by: Np143
I installed my fill valve seal on a Fluid Master 400, so I cannot advise you on this question. The fill valve seals are not very expensive so I’d give it a try before purchasing another fill valve assembly.

Does this valve seal fit the Fluidmaster 703A5B valve on my Niagara toiled?
Asked by: Ronn
The fill valve seal that comes in the 400A is also the same seal used in the 703. If you want to purchase just the seal it's a model number 242.

will this fit the fluid master 703A5B flapper?

Asked by: Ann
??? This seal is for a fill valve, NOT the flapper. The answer should be no so I do not know why people are saying yes.

how do you know what fill valve you have?

Don't have a manual
Asked by: Bob
You need the brand name and model of the toilet. Usually you can find the model # under the tank lid. Sometimes you just have to take the part in and match it up.

Hello, Will this fit the Kohler GP1083167 Silent Fill High Rate Toilet Valve? Thank you

Hello, Will this fit the Kohler GP1083167 Silent Fill High Rate Toilet Valve? Thank you
Asked by: JF
Yes it will replace the current fill valve in that toilet. The one in there now is a Fluidmaster 400 Series. The GP1083167 is a number Kohler uses to identify the product with them only. The 400a will replace it but it will be faster but louder. If you want the quietness that you are currently getting then we recommend to pick up a 400AH or 400H-002 Performax fill valve.

Will this stop from the toilet constantly running? I have a hrdoclean and it slightly leaks up top and the toilet keeps

The toilet keeps running into the overflow valve.
Asked by: PhillDL
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.

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
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.
