My problem is not exactly that they leak... I pull the plunger up, fill it with liquid and as I carry the syringe over to the boiler or burner, the plunger doesn’t stay put and slides back in pushing out the liquid.
Yep.....just discovered that myself. The weight of the glass plunger is enough to start it sliding down.
Amazing to look at how well they've made these though, the ground glass finish and fit is exceptional.
Yes, they sure do look nice, maybe it’s just a learning curve...
Did your’s come with an o-ring laying at the bottom (at the end of the plunger)? I assume it was just for shipping purposes to keep it from rattling around as I see nowhere to use it...
