More Capacity. Same Smart Design. Built for Longer Adventures.
When a weekend away turns into weeks on the road, you need a grey water solution that keeps up. The Fleximake Grey Water Bladder 40L is an Australian-made, foldable waste water tank built for caravanners, camper trailer owners and extended 4WD tourers who need a bit more capacity without the bulk of a rigid tank.
More and more campsites, national parks, caravan parks and rest areas across Australia now require travellers to arrive with a self-contained grey water solution. The 40L bladder gives you the capacity to go longer between dump runs while keeping your setup fully compliant.
The 40L bladder is the go-to choice for families, couples on extended trips, or anyone running a larger setup. Like its 20L sibling, it folds completely flat when empty for easy storage in tight spaces. The integrated lifting straps mean you can carry a full bladder comfortably and safely to the disposal point without awkward manoeuvring.
Fleximake has been manufacturing flexible bladder solutions in Melbourne for decades. Trusted by thousands of caravanners and 4WD tourers across Australia, their products are built tough, practical and space-smart.
