摘要： Disclosed is a coupling assembly for pipe connection, which, even when connecting pipes having different diameters to each other, can reduce the resistance against a fluid flowing inside the pipes, can be installed in a state where couplers are temporarily assembled using fastening members, and is not deformed during the fastening process and thus can also be stably fixed after the fastening process.

摘要： The invention relates to a method for connecting a connection section (33) of a hose (3) with a plug-in connector (4). The plug-in connector (4) comprises a connector body (6), which connector body (6) has a ring space (22). In a first method step, the connection section (33) is pushed into the ring space (22) of the plug-in connector (4) of the hose (3) from the hose accommodation side (25) of the connector body (6), and positioned there; in a second method step, a pressing tool (50) deforms the first mantle section (12) of the connector body (6). The second mantle section (15) has a narrowing (39) at a front edge (38) of the hose accommodation side (25), whereby it is ensured that the connection section (33) of the hose (3) is freely deformed in the direction of the second mantle section (15) during the pressing process, at least in the region of the ring space (22) that is at a distance from the front edge (38), before the connection section (33) of the hose (3) comes to lie against the second mantle section (15).

摘要： A universal fluid system connector creates an airtight seal between a variety of smoke evacuation system receptacles and various hoses. The universal connector includes a body and a seal having a plurality of radially extending flexible fins. A plurality of fins on the seal are disposed along the length of the body with the outer edges of the fins forming a frustoconical shape. The fins also include one or more flexion zones of various stiffness and one or more flexible fin extensions. The fins deform against the inner wall of a receptacle and form an airtight friction fit between the universal connector and the receptacle, regardless of the taper angle, size, threads, or other features of the receptacle.
