ACRC100 Air venting hose?

[Anonymous user]

We own 4 ACRC100 units and are going to have a chilled water outage to them in the near future.

Our Facilities staff decided to not continue the APC maintenance on the units, so we'll need to do the startup ourselves following the outage. I was wondering if anyone knows of a source (or even the name) of the nice venting hose that the APC tech had at the startup service for venting the air out of the purge valves in coil during startup? We'd like to have one on hand instead of using a small screwdriver...

Thanks!
