Circo PVC fittings are designed to fit standard schedule 40 PVC pipe with very few exceptions.

However, our Snap Clamps, Grip Clamps, Snap Hinges, and Cable Clamps have additional applications. Please take note, these items were designed for a specific fit but may also fit other applications not listed. If you need help with sizing please give us a call.

 

 

 

Snap Clamps are labeled according to the standard schedule 40 PVC measurement. 

*Example: a #11 (1/2") Snap Clamp will fit snuggly around a 1/2" standard schedule 40 pipe.
