Information
GN 283 swivel clamp connector joints are an assembly of GN 273 and GN 275 swivel clamp connectors. Since the swivel clamp connectors have an identical swivel width "b," all bores "d1/d2" can be combined as needed.
The clamping bore is machined and designed for construction tubings GN 990 or DIN 2391, DIN 2395 and DIN 2462 respectively.
In the standard version, the clamping force of the clamp onto the tube is achieved via the socket cap screws and hex nuts with nylon insert.
