In the fast-paced world of trenchless pipe rehabilitation, efficiency, durability, and adaptability are critical.
Flex150 calibration hose from James Dawson, a Fenner Precision Polymers brand, has been developed with exactly these priorities in mind, bringing a genuinely innovative approach to CIPP (Cure In Place Pipe) operations, particularly for UV and LED curing systems.
What sets Flex150 apart from single use calibration hoses is not just its reusability, but also its flexibility and exceptional expansion capability of up to 150 per cent, allowing a single bladder to accommodate a broader range of pipe diameters, reducing the need for multiple diameter hoses and more importantly saving you money on inventory stock and allowing for faster project work.
It lends itself well too, to residential pipe work repair.
Flex150 is engineered to meet the demanding and unforgiving nature of CIPP repairs.
Its toughened silicone delivers exceptional tear strength (30N/mm) and has been tested under extreme conditions, including 200 per cent extension at 150°C for 16 hours before returning to its original shape with minimal deformation.
This resilience enables up to 60 reuses, making Flex150 not only robust but also highly cost-efficient over its lifecycle.

Faster Curing, Faster Projects
Time is often the most valuable resource on any infrastructure project. Flex150’s is designed for enhanced translucency, a key factor in UV and LED curing applications.
Independent testing has shown the hose to be 10–30 per cent more translucent than comparable reinforced hoses at higher wavelengths. This increased light transmission allows more energy to reach the resin liner, resulting in faster and more efficient curing.
