End cap keeps popping off


#1

Hi!

The end cap keeps popping off when I put it on my v2.8.

Does the strap fix this when properly tightened?

Thanks!

@rdbiv,
Are you putting the end cap on with the plunger removed?
If not, you are compressing the air in the tube which when heated by the OROV 2.8 controller board will push the end cap off.

I was removing the plunger as you describe, later figured out through trial and error that I over lubricated the o rings.

New problem: Water is leaking in through the vent/the plunger is only partially sealing the vent.

I’ve replaced the plunger and still have this problem.

Do you know a way to ensure it will seal without replacing the syringe end?

Thanks!

@rdbiv,
For a start, I would thoroughly clean the bore of the syringe with a Q tip soaked in 90% isopropyl alcohol to insure that the walls of the syringe bore are clean. Then clean the plunger O ring and lube just lightly with the silicone grease.
You might want to take a picture of the syringe end of the end cap so we can see if you cut the end of the syringe off correctly.

Ok, will do.
