How to Choose Fitting Size and Material
- Size: match the fitting to the pipe or hose you will connect. A 3/4" fitting suits a sight glass or a small drain line; 2" and 3" fittings move more water for outlets, drains and transfer lines.
- Position: a bottom drain flange empties the tank from its lowest point; a side or top flange goes where the outlet or fill line needs to be. Check that the tank wall has a flat area wide enough for the flange.
- Valve type: a full port ball valve opens to the full pipe size for faster flow; a stubby valve has a short body that sits close to the tank.
- Material: pick a fitting body and gasket your liquid won't attack. For water, polyvinyl chloride (PVC) or polypropylene (PP) with an EPDM rubber gasket is common. For chemicals, check both the fitting and the gasket against what you store; Peabody Gemini bulkhead interconnects come with EPDM or Viton seals.
Fitting Materials in Our Range:
- Polyvinyl chloride (PVC)
- Polypropylene
- Polyethylene (PE)
- EPDM rubber or Viton seals
