Large choice of diameters & lengths
Long-lasting & high-quality product
Our flexible bore water hose is totally corrosion and microbiological damage resistant and will not succumb to iron bacteria build-up.
Intended use
Flexibore systems are intended for upstream raw water transfer only, and it is assumed that suitable filtration and treatment are installed prior to connection to regulated potable water plumbing systems.
Features
- Deep bore capability – pumps water reliably from depths up to 250 m
- Ultra-high tensile strength – supports heavy submersible pumps and full water column (up to 21 t peak load)
- High burst pressure – up to 7,400 kPa depending on diameter
- Dilates under pressure – up to 15%, reducing friction loss and preventing iron bacteria build-up
- Flexible & lightweight – simplifies installation and rapid retrieval compared to rigid pipe
- Secure guide strip with cable loops – prevents cable abrasion inside bore casing
- Secure quick-fit couplings – robust, leak-free, and easy to attach on-site
- Available in a wide range of diameters (40 mm – 152 mm) and continuous lengths up to 500 m
- Proudly Australian Made & factory tested
Primary uses
- Bore water pumping (up to 250 m)
- Mine dewatering with large submersible pumps
- Agriculture and irrigation requiring high volumes at depth
- Industrial and municipal groundwater extraction
- Potable water supply (AS/NZS 4020 certified)

Frequently Asked Questions
FAQs
There are 3 recommended methods for safely installing pumps with Flexibore® : vehicle assisted, crane assisted, and hand assisted. The method chosen will depend on the bore depth, pump weight and access space.
Flexibore® couplings are designed to be fitted onto the hose during installation. Once the coupling has been attached to the pump, the hose is pushed onto the coupling tail; 2x 3-piece clamp sets are then securely fastened around the hose using an Allen key.
There are 2 methods to secure the power cable to the hose: Crusader Hose-approved heavy-duty cable ties & FlexiStraps.
As long as the total weight of the pump and cable falls within the safety margin of the max. tensile load, then no safety cable is required. If the total weight is higher than the recommended max. tensile load, please contact us to discuss safety cable usage.
