The KUPO C-23 Pipe Joiner is a heavy-duty external connector for joining 48 mm tubes in fixed pipe structures. It uses eight hollow 3/8" set screws to lock the tube ends while allowing the installer to visually check pipe insertion position before tightening.
Why It Matters
A joiner is only useful when both pipe ends are seated correctly. The hollow set screw arrangement gives installers a practical check point during assembly, helping the connection stay about alignment and insertion depth rather than guesswork hidden inside the sleeve.
Key Features
External steel joiner connects two 48 mm tube sections in fixed pipe structures
Eight hollow 3/8" set screws secure the tube ends and help check insertion position
Black powder coated finish matches low-visibility pipe-grid hardware
WLL is not rated, keeping the part positioned as a connector rather than a lifting-rated hanger
Applications
Use it for joining 48 mm tube sections in fixed pipe grids, venue structures, and installation layouts where alignment between two pipe lengths is required.
Compatibility
Use only where an external 48 mm tube joiner is appropriate. Do not present C-23 as a working-load-rated lifting component, since the specification lists WLL as not rated.
Frequently Asked Questions
Is C-23 rated for lifting?
No. The specification lists WLL as not rated, so it should be treated as a pipe joiner, not a lifting-rated hanger or suspension clamp.
Why are the set screws hollow?
The hollow screws allow visual check of pipe insertion position, which helps installers check that both tube ends are properly seated.
What tube size does it join?
C-23 is made for joining 48 mm tubes.
