Gen 2 Replacement O-Ring Set for RAPT Pills.

This set features a Silicone Brown O-Ring and EPDM Black O-Ring. This particular material combination aids in sealing and permeability. By having EPDM in the mix it will slow down CO2 transmission into the pill, and by having Silicone in there it will be able to seal more effectively at colder temperatures (shrinking / memory of material).

We would always recommend putting the Black EPDM O-Ring at the top of the thread (see picture)
