Yeah, I reckon that's the chance you take when you buy cheap chinese products off the internet. You get what you pay for. Then again I've had similar experiences with marked up cheap chinese products that I've bought locally.keifer33 said:I purchased a few of those ebay fittings and found when left submerged say during the mash they had rusted on the outside. All of the internals where fine. So it can be hit and miss. I am still using some as external fixings on herms and inlets.
