tolerances, except on the outside of bends where the thickness may be
reduced slightly in manufacture by usual commercial methods. Inlets shall
have rubber washer and copper alloy nuts for slip joints above the
discharge level. Swivel joints shall be below the discharge level and
shall be of metal-to-metal or metal-to-plastic type as required for the
application. Nuts shall have flats for wrench grip. Outlets shall have
internal pipe thread, except that when required for the application, the
outlets shall have sockets for solder-joint connections. The depth of the
water seal shall be not less than 50 mm 2 inches. The interior diameter
shall be not more than 6 mm 1/8 inch over or under the nominal size, and
