Pit-Hole Repair Clamp
The stainless steel Needle Clamp is a pit-hole repair clamp and is the appropriate solution to repair small corrosion pits in steel pipes.
No surface preparation is required and a simple wrench is sufficient to install the clamp.
The needle guides the tip of the conical rubber to enter the corroded area. By tightening the plug, the rubber (NBR or Viton) sufficiently compresses to seal off the leak.
Maximum working pressure is 2000 psi (138 bar).
