That’s a STRAUB-GRIP-L Pipe Coupling 🔧
You can see it stamped right on the metal: STRAUB GRIP-L
What it’s used for:
This is a heavy-duty pipe coupling used to join two pipes together, or to repair a section of pipe. It creates a pressure-tight, leak-proof connection without welding.
Key features:
1. Outer shell: Stainless steel housing for strength and corrosion resistance
2. Inner seal: Black EPDM/NBR rubber gasket - creates the watertight seal
3. Grip rings: The teeth you can see inside bite into the pipe to prevent it from pulling out
4. Bolts: Tighten them to compress the seal and grip the pipe
