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
