Dräger second medium-pressure connector Part # 3358868

 The second medium-pressure connector that
 integrates into the medium-pressure system of a Dräger PSS® Series
 breathing apparatus. It is connected into a port on the pressure reducer
 and provides the wearer with two connectors as follows:
 ● An outlet connector (female quick-connect coupling) is used for the
 supply of air to a second person for the purpose of rescue.
 ● An inlet connector (male quick-connect coupling) is used for the supply
 of air from an alternative medium-pressure air source for
 decontamination.
 There is a one-way valve in the inlet connector of the PSS® Buddy
 Breather that normally blocks outlet air flow from the connector. A safety
 feature is that the outlet connector of the PSS® Buddy Breather has an
 actuator coupling (AC) that overrides the one-way valve if two PSS® Buddy
 Breathers are connected together. This ensures that if a second PSS®
 Buddy Breather is accidentally reverse connected during a rescue, air is
 still supplied to the second person
