Smooth Joint™ Technology

6.9” O.D. SDR21 F/T PVC (NSF)

THIS JOINT’S GOT GRIP

Compared to spine lock mechanisms, which use only one or two grooves, Smooth Joint™’s flush-threaded mechanisms have multiple threads per inch at each joint, evenly distributing the vertical suspension weight over a larger surface area.

Advantages of Smooth Joint™

  • Consistent O.D. allows for a smaller borehole, and no bulky joints.
  • Extra inches added for shoulder-to-shoulder
  • Fits all custom pumps
  • Outperforms belled and spline lock PVC.
  • Offers better tensile strength
  • Easier installation, just twist and use.

Do the Math

Tests show the tensile strength of Smooth Joint™ far exceeds ASTM F480 suspended weight specifications.

  • NPS 6.9” O.D. SDR21 Smooth Joint
  • ASTM F480 Specification: comparable to our competitor
  • NSF approved PVC
