ABSTRACT:
In pipe coupling systems, elaborate equipment and tools are required for their assembly and disassembly; the disassembly procedure is time consuming and little, if any, of the fittings can be reused.
The present invention relates to improvements in pipe attachment system to their fittings, particularly adapted for use with smooth surface pipe and tubing where assembly and disassembly is easily made with simple tools or without tools.
Except for the sealing ring, all parts of the system are reuseable without special preparation.
