The Q.R FLEX connection is a new generation of vibration-resistant connections that provides proper angular and axial deflection as well as resistance to dislocation by eliminating any bolts and glands. The sealing gasket of this connection is similar to the Tyton and R.J Pipe connections, and therefore the force required to install this connection is similar to the Tyton connection. This connection is designed in accordance with the international standard ISO 16134 and has been functionally tested in accordance with the international standard ISO 10804. Improving the angular deflection compared to the first generation from category three to category two, eliminating the gland, improving disassembly operations and creating the ability to be used in trenchless pipe laying are among the advantages of this type of connection. Currently, this connection is designed and manufactured in three sizes: 150, 200 and 250 mm. The purpose of producing this connection is to replace part of the first generation connection with this type of connection.
