Piston-in-a-tee questions

[Modderxtrordanare]

So a 1.5" piston sealing against a 1.5" pipe is fine? Or should I step down the pipe to 1.25"?

A 1.5" piston will work sealing against 1.5" pipe. (My piston was a 1.5" cap, so it's a little bigger and thats why it works.)

my piston was going to be a plug, so the diameters are exactly the same.

If you are using the flat end of the plug and not the pipe end (hopefully ) then it will still work.

Yeah. I'm using a DURA brand plug. They have the "wall" on the opposite end as the hex. So I chop the hex off, bolt on a piece of rubber, and I have a piston.

As long as they can be the same diameter I'm good to go. Thanks guys.
