Often get told you can't re use forks seals to good effect,
obviously if damaged, nicked, torn etc
though the what if in me often gets me questioning reasons
as to why you can't to all manner of things.

For the past couple of years I have been re setting and re using my fox fork
seals on my 32's and 36 forks and with no ill effects to date.
With around ten sets of fox forks on the go on various bikes
this has certainly saved me from having to purchase new seals on
a regular basis.

On stripping a fork down for service I remove the seals and garter springs,
clean them of any grime then submerge them in a type of paint thinners,
( type of thinners and time are relevent here ) after a short time the seals
absorb the thinners causing them to enlarge by a noticable amount,
this also softens them, after some time remove them from the thinners and
dry the excess then leave over night to evaporate.

After all this they re set to there original shape and firmness.
This has cured seals that have previously weeped oil on the stanchions.
The foams rings disintergrate after a few minutes so if these are good to re use
then its a quick drop in and then squeeze out the thinners and let it
I'm still using the old type flange lip fox seals.

Your thoughts or similar to this, what are your ways on re using seals
or other parts that are actively encouraged to replace,
be interested to hear.
