Notes:
*Dimensions subject to change at our option.
For Fastite pipe dimensions, see Pipe Joints (Section 2).
For Flex-Ring and Lok-Ring pipe dimensions, see Restrained Joint Pipe (Section 9).
Fittings furnished interchangeably as Fastite or Flex-Ring may have the same dimensions/appearance (e.g. Flex-Ring per the bottom cut) in many sizes and configurations.

Notes:
*4"-14" Fastite Plain Ends and Flex-Ring Ends are not available on most fittings.
**The laying length of fitting plain ends is not necessarily the same as the gauge length. In general, depending on the fitting configuration (C110 or C153, etc.) and also the size and joint, the laying length of a fitting plain end will be approximately 8"-10" longer than the laying length of the same fitting (with a) bell end. Contact AMERICAN when more precise dimensions are required.

Maximum Allowable Separation
Push-On Fitting Joints

Joint Dimensions | End Standard Dimensions
Allowable Separation and Deflection | To Top of Page

Maximum allowable separation, "S", in a push-on fitting joint is approximately equal to the median pipe diameter in inches times the sine of the deflection angle. This is provided for information only and should not be used to determine precise joint deflection.
