I came to this mod because I had broken the front part of the plunger on one of my night finders, but after finding this out, I did it to my other NF as well.

As you know you can unscrew the plunger head off of the spring stick, if you do you can pull apart the two plastic parts that, with the o-ring, make up the plunger head. Now you can throw away the screw and front plastic part. (Screw is too short to use with this mod)

Then at Home Depot you can buy from the toilet section a fluidmaster seal (242). A replacement seal for fluidmaster 400A fill valve. They come in a red and green package.
Then go to the screw and bolt section and get machine #4-40x3/4" round head slotted 8 pcs. 27461 pack (green).

Now take the seal. The side that has the nipple will be facing out; the other side will be facing the back plastic part. You need to trim the lip off of the seal and cut the corners off of the plug on the side facing the plastic back. Also cut off the nipple.

Now take the screw and put three bolts on it. Then push it in the rubber part. Then put the parts together, going seal, o ring, back plastic part. Then screw it back on the spring stick. You’re good to GO!

Now you have a plunger that handles getting hit and now has a double seal. Also it allows you to use a stronger spring with out breaking the plunger head.

I know this is a very old post, but this sounds like an interesting idea. How was preformance? What were your ranges? Was there any friction?
