Sticky Syringes !

[The Hat]

I have been using my syringes quite a bit over the past week doing maintenance and cartridges purging and some of them have gotten very hard to pull and push on, and some have come apart on me thankfully mostly with water in them.

I have found a good way of solving this problem, by putting a drop of Propylene Glycol on and in between the upper and lower O rings on the plunger, I used my finger to apply.
Works like new..
