Notes
- For tolerances and additional dimensions, see AWWA C111.
- Bolt holes are 1⁄8" larger than the bolt diameters.
- Mechanical joint retainer gland designs (by others) often require longer standard bolting than shown above. See Mechanical Joint Pipe and Historical Data regarding alternative restrained joints, and also retainer gland applications.
Mechanical Joint Plain End
The “L” dimension is minimum length of the plain end which must be gauged to ensure the outside diameter is within the dimensions and tolerances required.
The laying length of a plain end of an MJ fitting is 8" longer than the laying length of a bell end.
Plain ends of fittings may be furnished with beveled ends for assembly with either Fastite or mechanical joints. However, if beveled ends are required they must be specified.
