removing p-connector from old lungs

OceanOpportunity · 18th January 2008, 18:44

Hey all,

trying to remove some p-connectors from an old set of Dolphin lungs. They 'look' like they just unscrew into two parts, which should be easy enough. Mine are stuck, and before I break anything, wanted to make sure there are no tricks.

probably just alot of old salt and other crap in there

yup, the standard p-connector is two parts, the "connector" which sits on the outside and a locking ring on the inside.

Soak them in hot soapy water. or put them in the fridge..then try opening them when there cold,... not frozen

The only way I was ever able to get them freed of old Dolphin lungs included destroying the lung. Draeger has some sort of fixture to thread them on that torques them so tight that you cannot believe it. I cut a slit in the fabric a few inches away, and rip the fabric by hand along the line of the weave, right up to and then into the flange of the P-Connector. The fabric can then be pulled out of the fitting flange, and the P-connector will then unthread with ease. Back in the old days the easy way to get (3) P-Connectors was to buy a new lung and remove the connectors. It was cheaper than buying 3 individual connectors.
