Hi - I am Technical Manger at OmegaFlex, manufacturer of TracPipe. Depending on what size you will need the 90 degree bends can be pulled quite tight. For example, a DN22 pipe can have a minimum bend radius of 25mm whereas a DN28mm pipe has a minimum bend radius of 76mm. I can also confirm that TracPipe can be used both internally and externally as well as being buried directly in the ground or screed without additional corrosion protection. As has been highlighted flux is an issue with any stainless steel product so ensure all soldering is completed and flux residue removed before connecting to the TracPipe. I also note that someone has likened TracPipe to using an 'Anaconda' (meter inlet connector). This is also true but the key difference is that meter inlet connectors have to be annealed during the manufacturing process which makes them quite soft and susceptible to damage. TracPipe is not annealed and is therefore very strong and in fact stronger than copper. Cost is always a subject that comes up when using TracPipe compared to copper - but it is worth remembering that TracPipe can be up to 3 times quicker to install and typically you will only need two fittings. Therefore overall the installation can be cheaper but more importantly, safer! Happy to discuss this further with anyone interested so please give me a call of 07795 181472 or visit
