Information
The clamping bore of GN 277 swivel clamp connectors are 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.
GN 275 swivel clamp connectors can be assembled with swivel clamp connectors GN 271, GN 273 or GN 275 to create swivel clamp connector joints.
