Are you talking about the O-ring? I make my own. Buy the right sized O-ring cord and cut it to size and super glue the ends. Dave Germain

 

O- Ring

You can,t just use any kind of O-ring material can you? Also, there is a specific theary on how it works isn"t there? Size, compression etc. If you can help let us know. Thanks Don

ø1/8"

If its "1/8" o-ring be careful, there is some o-ring material a little larger than .125, like .139.

 

I looked it up with Mcmaster Carr catalog, I think I'll try neoprene... compresses well and does'nt take a set and is rated "good" for akly, unlike buna N or viton which are rated poor or not recommended. Kalrez is tops but it's as rare as hens teeth. Have used viton before and it always seems to swell up after awhile.

 

Flourocarbon / Viton - Gasoline ONLY


Nitrile / Buna-N - Methanol or gasoline - NO NITRO


Ethylene propylene / EP or EPDM - Nitro or Methanol - NO GAS

This is the chart I use for choosing o-ring materials.
