Hi,
I have four tiny but very expensive O-rings used for dust scraping
around pistons in motorcycle brake calipers. Thay have expanded due to
an oil leakage and I hope that it's possible to shrink them again
somehow.
I know very little of polymers, but the O-rings are brake fluid
resistant and apparently not transmission oil resistant. Looking at
this list:
The rings could be made of EPDM (Ethylene Propylene) but that is just
an unqualified guess.
The rings feel like they haven't changed properties beside the
expansion which makes me hope that it is possible to shrink them
again. What do you, dear readers, think of this?
Thanks in advance.
