1 Not included in AWWA C110.

2 Based on performance testing per AWWA C153, AMERICAN can rate these fittings 350 psi. However, because of the more labor-intensive and labor-reliant assembly of the mechanical joint and the substantial thrust restraint requirements for working pressures that high, we recommend push-on joint configurations (Fastite, Flex-Ring or Lok-Ring) for high-pressure applications.
