Pneumatic fittings are the super speed fit push-fit fitting specifically designed for miniature pneumatics applications. These fittings are fast and safe way to join tubes and provide advantage over other conventional fittings.he assembling of complex tubing system has become easy due to simple and swift disconnection of these fittings, less maintenance for easier functioning and fault finding. For making connections a tube is normally pushed in by hand; the system holds strongly in place without disfiguring it or restricting flow.
