just going to fit a new s flange to the top of a cylinder, is it better to fit straight onto cylinder without the 50mm brass spacer so the inlet is 50mm deeper into your cylinder?
No instructions supplied with it! Empty box? But have since found on line if you use the 50mm spacer it has female threaded end, if not its male threaded end. Cylinder is female thread so not used it and it goes 50mm deeper so better for all
