Annoyed with thread on Schrader chucks or clamp on's that lose air?Our #Silca Schradero chuck eliminates the hassle with a simple press on locking action and sliding sleeve quick release mechanism that provides next to no air loss. A perfect companion for a compressor and available in both a threaded and barbed end. It's one of those items we love and feel like few know about!
