O-lets are widely used abroad in recent years and used as reinforced pipe fittings to connect pipe branches, to replace traditional connecting types such as reducing tees, reinforcing plates, reinforcing pipe sections. Being safe, reliable, and easy to use, they reduce cost greatly and improve medium flow passage, which combines with their standardization and convenient design selection, have contribute their wide adoption in high-pressure, high-temperature, large-caliber and thick -wall pipes, replacing traditional connecting types of pipe branches.
  
O-let bodies use high-quality forged pieces, and their materials are the same with those of pipes. We offer carbon steel, alloy steel, stainless steel and more materials for selection.
   
O-lets and main pipes are welded, and the connection of o-lets and pipe branches or other pipes (short pipes, plugs, etc.), instruments, and valves features many types including welding, socket, and threads.
   
The type of o-lets are divided into standard, nipolet, latrolet and elbolet.

All o-lets in this site are suitable to inch pipes, and o-lets that are suitable to metric pipes (excluding threaded pipe type) can also be produced. Please indicate following items in the order:
Type code (o-let and connecting type);
Pipe branches and their nominal size (OD is required for metric pipes)
Pipe branches and their wall thickness levels (wall thickness is required for metric pipes)
Pipe thread code (only refers to threaded pipes)
Height (only refers to nipolet)
