Ring Joint International Co., Ltd.  

Thank you for your interest in the new RING JOINT
piping connector technology. This inovative approach is extremely cost effective
in both initial cost and in labor savings. The complete line of connectors include
both metric and (NPT) National Pipe Thread standards ranging from 1/2 inch through
3 inch, and operates on all standardized piping of copper, aluminum and stainless
steel.

Applications in any industry where a solid and fluid
  tight seal is required would demand the superior quality and fitness of the
  RING JOINT connector technology.

This No Sweat...No Solder... No Mess... No Hassle...pipe
  connector method is one of those inovative technologies that you
  will wonder how you ever got along without. The problems of solder and weld
  pipe j oints will become a dim rememberance of the past.

We are very much looking forward to serving your needs in this area. Please
  feel free to contact your RING JOINT distributor
  for any technical assistance.
