Inhalation Port Cover (CIP-GEN4-3M)
Attention: Due to limited availability of the antimicrobial material, all affected items are currently blue instead of the usual red.
The Cover-Inhalation Port, Gen 4 (CIP-Gen4) is a bayonet cap that will shut off an inhalation port on the 3M 6000 series half face respirators. The goal of the CIP was to block one of the two inhalation ports securely, while also being minimalist in profile. We certainly weren’t the first to conceive of an inhalation valve cover. 3M makes a port cover (part number 6880) but they are limited in availability. Others have put out their own versions of a 3D printable port cover, however many of the ones we‘ve seen are not as low profile as we desired. The CIP does fit on the 3M 7000 series masks as well, but the fit may be more tight than necessary due to how the 7000 series masks use the silicone body as a face seal.
The CIP-Gen4 is the forth revision of our current design and features:
• Knurled outer perimeter to aid in installation and removal
• Low profile design
• Inner plug* with an o-ring for additional sealing (dash 112 o-ring installed)
• 3D Printed from specialized antimicrobial/antibacterial plastic material, and alcohol washed and bagged.
The CIP inner plug’s o-ring is optional. Once the CIP is locked down into the mask’s inhalation valve’s bayonet interface the flat bottom face of the CIP forms a seal with the inhalation gasket. The o-ring just provides a secondary seal(Note: the CIP’s o-ring is optional, but the orange OEM 3M inhalation-port-gasket ring MUST be used). O-ring size is dash 112 (we’ve been using nitrile o-rings, silicone are probably fine also). You can size up or down if you find the fit with the o-ring to be loose or too tight. We’ve seen slight tolerance variations on the 3M 6000 series mask over various years of production.
