Review: Purge bungs - I use it for purging pipework great bits of kit
Review: Stiff thread makes it difficult to fit. - I had to use grips on the threaded section to stop the whole thing turning while i tightened the wing nut. It does seam to seal okay once in place. Not as good as the Bailey version which uses a nylon nut and has softer rubber.
