Hey there! If you need some seriously stretchy tubing for your lab or equipment setup, this natural latex rubber hose is exactly what you're looking for. With a 1/2 inch (12mm) inner diameter and 11/16 inch (17mm) outer diameter, this 10-foot tube is super flexible and durable. Made from 100% natural latex, it's perfect for connecting different instruments in laboratories or any application where you need high elasticity. Just cut it to whatever length you need - super easy! A quick tip though - keep it out of direct sunlight when storing, and if you're not using it for a while, seal it up in a plastic bag to keep it in great condition. This stuff is seriously tough but stretches like crazy, making connections between different sized fittings a breeze. Whether you're in a professional lab setting or working on a DIY project, this tubing has got you covered with its reliable performance and natural material construction.
