The Inhale and Exhale T-Piece Mesh Caps are threaded caps with 316 stainless steel mesh filters. They allow the counterlungs to breathe when drying the unit after cleaning while keeping insects from entering the loop.
Sold as a pair:
- 1x Exhale cap (RB15A) has a fine thread suitable for either port of the right shoulder T-piece
- 1x Inhale cap (RB15B) has a coarse thread suitable for either port of the left shoulder T-piece
If you prefer to remove the hose & mouthpiece assembly when washing and drying, and so want to cap both ports of each T-piece, then you will need 2 pairs.
