I purchased stainless steel fittings for a pressure application as they are pressure rated on the site, see part numbers 14014, 14013, 14057, 14058, 14060, 14014, 14114, 14024, 14004, however, when asked for the datasheet on two subsequent occasions (21/06/2022) and again on (07/06/2023), I have been told: " Hi, Unfortunately, our overseas supplier does not offer a data sheet for this Contract product Regards" Clearly, these fittings are not pressure rated if the manufacturer will not provide a datasheet! Why are they being mis-sold? I have tried contacting returns however, both of my emails have been ignored!
