This item description, while accurate, is misleading. The threads do in fact measure what is specified in the posting, but the threads are metric, or imperial or something, not SAE or standard American pipe thread. If you're in the USA, this will not fit a standardfemale pipe adapter, just want to share my experiences with everyone. It can be made to work with a PVC adapter if you cut most of the threads out with a utility knife and force, force, force the silencer in, but it ain't easy by any stretch. My advice is to stay away from this if you need standard American threads for your project. And my advice to Amazon is try to include a better description for your foreign sellers' articles.
