I purchased all Hayn fittings when we re-rigged the boat in '06. I found in their descriptions there was no mention of lubricating the threads prior to refitting them. One of the fittings galled. I'd actually never had this happen before. However when I called Hayn's distributor they promptly shipped me a replacement fitting. In addition I never found in their literature that 1 x 19 wire needed a different wire sleeve for Dyform wire. In 2020 I see that the fittings have different listings. They shipped the correct former the same day.
Now in 2021 I am in Australia and need to do some replacement rigging. As there is only metric wire anywhere in Australia I need some new formers. I've ordered them and am awaiting the new ones.
