Hi Ken.
Thanks for using ECO Funnels! Inside the lid of our ECO Funnel, there is a closed cell polyethylene gasket that will “hiccup” with needed.
Otherwise we have a couple types of Pressure Relief Valves.
One is our Vent Filter, for minor pressure.

For more pressure, we can attach the following:

Hope this helps. I’m glad we were able to accommodate your pressure relief needs in the manner you needed!

For collection, we use the CP Safety eco funnel http://www.calpaclab.com/about-the-eco-funnel/
We had pressure reliefs installed on the lids. Normally they install them on the sides but we were concerned with clogging. The lids will also pop before the pressure is so great that the bottle would rupture. The vent is only as safety
precaution in case something was not quenched properly. Nothing is routinely vented. I can not say that anything has ever come out of the vents.
