Gets the job done
Would RecommendThe Proline series compression cap is pretty straightforward. If you have a threaded valve that needs to be stopped then this is what you need. I had a valve with two stems and didn't want to replace it with a single stem valve. This cap helped block the other stem without any leaks.
