Composite Water Service Tubing Combining the Benefits of Metal and Plastic

Manufactured by IPEX to AWWA C903-02, Q-Line® is the only water service tubing in North America that delivers the strength of metal, the flexibility of soft copper, and the durability of thermoplastic. And because it eliminates the shortcomings of traditional piping materials, Q-Line® is superior to them all.

A High-Performance Tube System

  • A composite pipe constructed of flexible aluminum tubing permanently bonded between inner and outer layers of raised temperature polyethylene (PE-RT), Q-Line®’s unique structure offers optimum strength and toughness in a lightweight, easily handled and installed water service tubing
  • Q-Line®’s high pressure and temperature ratings ensure water service line integrity under the toughest operating conditions and protect against the effects of any backup of hot water from the building into the water supply system
  • With larger inside diameters than CTS polyethylene piping and a super-smooth interior wall that does not permit build-up of calcium or other minerals, Q-Line® offers the best flow rates in the industry
  • Simply roll Q-Line® tubing down the trench and it stays where it’s laid (unlike plain polyethylene). Goosenecks and bends can easily be made just like copper, and Q-Line® keeps its shape
