GL14 pressure equalization port

This GL14 cap fits onto pieces like https://www.thingiverse.com/thing:4960458 and https://www.thingiverse.com/thing:4958064 . I use it with an autoclavable resin and attach a tubing / sterile filter set to the top port after sterilization. Along with a 3x GL14 to GL45 adapter, it can be used on the top of a standard laboratory bottle for pressure equalization.
