Bag penetrators create air tight passage through plastic bag. Their special sized threading avoids damaging bag material as they screw into place.

Bag Penetrator 22 mm Adapters pass filtered air into the Bunny PAPR. Their tapered end fits standard 22 mm ID fittings.

Bag Penetrator Flutter Valves pass expired gas out of the PAPR. Flutter valve provides additional user protection beyond continuous positive pressure differential.

Do not precut openings in your bags before screwing in penetrators. Penetrators have a double sealing action. Bag plastic is not just sandwiched between the flat parts of penetrator and its port. It is also deformed and molded between the special sized threads to seal like thread tape. Single mode sealing is likely sufficient, but both is best.
