I realized that the latex sacs in my repair box are about 10 years old. (still in a ziplock bag)
My question here is:
Should I order some new sacs before repairing some Wearever and Esterbrooks, or are the ones I have likely to be just fine?
This came up because I just received an E-Bay lot that needs service. The Parker 21's hold liquid, but are .. deteriorated. One is almost completely black - you can only see through it with a bright light behind it. So I'm going to be ordering some PVC sacs to re-sac the Parkers.
(The Parkers will be a separate post. One is a typical Parker 21, but the other is... odd. )
