You need to isolate a section of pipe for a quick service job and you don't want to drain the whole line. This 12mm Jaycar shut-off valve does exactly that. Quarter-turn operation gets you from open to closed in one snap. One important thing: it's built for full-open or full-closed only. Don't leave it half-turned to throttle flow. That's not what it's designed for, and it'll wear out the seal. Use it to shut off, do your work, open it back up. Sorted
