Connections
The air outlet features internal threading for compatibility with the included barb adapter; however, we recommend utilizing the provided rubber elbow when connecting 3/8" tubing. For larger tubing, direct connection to the smooth outer surface of the air outlet is suggested. The 14mm outlet is suitable for accommodating 1/2" tubing, while the 18mm outlet can support 5/8" or 3/4" tubing. Should you wish to use 1/2" tubing with the 18mm outlet, additional adapters will be necessary. Across all models where brass is employed to link to a septic pump alarm, the brass component measures 4mm.
