AdBlue Mann-Tek Fill Coupling

For spill free transfers of AdBlue between delivery vehicle and storage tank we recommend the use of the Mann-Tek dry break couplings.

All industry standard AdBlue (DEF) Storage Tanks should have this device fitted to ensure a spill free delivery during bulk transfer.

The coupling is supplied as a 70mm fitting with 2” BSP(F) inlet which can easily adapt to your existing fill point.

The spill free device utilises a dry break connection identical to that used in the aviation industry for filling aircraft and is precision built to military standards.
