If you don't want your aircraft tubing to look like an apocalyptic scene out of "Brazil," you'll need some help from professionals. Imperial Eastman is known around the world for their specialty tools specially designed for tube working, HVAC, industrial, automotive and electrical applications. Their brass flareless tube fittings are meant to be used with Poly-Flow tubing, and they're designed to prevent any weakening of the tubing. Their Nylo-Seal flareless tube fittings offer the same protection and do not require any flaring tools, wrenches, benders or other tools to install. You'll find a wide range of fittings, such as nylon insert stabilizers, male elbows, inline connectors, brass nuts with plastic sleeves, nuts, plugs, union elbows, run tees, branch tees, bulkhead unions and more. You'll also find their nylon tubing. Give us a call if you need assistance in figuring out exactly what you need.
