Section 2: BATT Fittings
Installation of Fittings
Description of Fittings
BATT fittings include:
•
Fill/discharge fitting, at least one per tank
•
Vent fitting, at least one per tank
Each fitting consists of two main parts: a part attached to the tank using an NPT connection and a removable
part attached to the first part using a quick connection. The vent fitting is complemented by a detachable
vent hose. It is recommended to have a vent hose installed and a hose end directed outside the fuselage
during tank venting in order to avoid contamination of the fuselage’s inner space with fuel splashes and
vapor. BATT fittings are supplied as pre-assembled units and don't require any additional assembly before
installation on the tank.
Thread Sealants
Thread sealant must be used during the installation of threaded fitting parts into BATT flanges.
Recommended thread sealants include:
•
Loctite 567 or Loctite 565 paste threads sealant or equivalent. These sealants are pref-
erable. They can be applied in ambient tempe 10 C or higher.
•
Loctite 55 pipe sealing cord
Important Note
For aircraft fitted with tail dragger landing gear, the vent should be installed in the flange closest
to the cockpit. For aircraft fitted with tricycle landing gear, the vent should be installed in the
flange at the center of the tank.
Warning
Do not allow the pipe fitting to cross thread into the flange as this will damage the flange thread.
This flange cannot be replaced in the field.
