I would keep this seal as a spare. Clutch slave has been known to fail after more than 10 years in use. Amazing thing is the cost is very low. One of my S10 friend had a clutch failure and manage to find a replacement seal off a automotive spare parts shop.
Here's the rubber seal for the slave clutch pump as replacement. Size 1-3/16". Part Number SC-40493R or SC40493R
An example in Aliexpress: https://www.aliexpress.com/item/1005003196757528.html. Not sure who made this but for a Japan made seal, Seiken. Daihatsu, Toyota Brake parts apparently uses this seal. Probably can get if off Parts Store for automobiles or trucks and buy the Japan made ones.
Alternatives:-
A complete replacement kit could be found here:

For original replacement for entire pump: (Online Japan shop)
