Four pack of O-rings for the BrewZilla Sight Glass stainless steel ball valve and elbow.

The PPSU Sight Glass uses radial sealing in order to not leak, even under pressure from a 25W pump. This is a very similar design to the Duotight fittings that also use two O-rings. Incase one breaks, or leaks, there is another to save the day.
