Special Fittings

This fitting is sometimes referred to as “bell mouth.”

Flare castings or fabrications can be furnished in a variety of lengths and with wall collars when specified. Any flange or mechanical joint bell to be installed flush with a wall should be specified “tap for studs.”

The addition of a wall collar to flare castings may affect the minimum length of the casting.

Other joints can be furnished in lieu of flanges or mechanical joint bells in most sizes.

The following fittings are not included in AWWA C110, so the dimensions for “L” and “C” should be specified on engineering drawings.
