The GGS Tuff Tube is precision moulded with an aluminum back stem and low-density core wrapped in a natural black rubber grip to significantly reduce vibration and eliminate flex. This combination solves the two most common issues plaguing conventional plastic disposable tubes. Comfort and durability are paramount to us when it comes to providing a quality disposable tube that you can rely on. We moulded our crystal clear high-flow tips from premium medical grade, high-slip plastic. They come in slash-cut round, slash-cut diamond, and open-wash magnum. Tuff Tubes are only available in standard 30mm (1.25”) grips.
