To accommodate the wider range of pipe sizes within the 10" and 12" categories, it is necessary that the center rings be made in different sizes: A x A, A x B, B x A and B x B. For example, 12" riveted steel x 10" ductile iron requires a 12A x 10B center ring. For RC501 parts list, see page 3-13 & 3-14. WARNING: Flexible COUPLINGS do not provide protection against possible pullout of pipe ends in unrestrained conditions.

5 CAUTION: COUPLINGS with a step in the center ring have the potential for migrating along the pipe. therefore some sort of restraint should be used. TO ORDER: Determine of pipes to be coupled. Select proper gasket range for each pipe from above table. Insert top range from each gasket, into the catalog number as follows: RC501 (one end x other end). EXAMPLE: To couple 6" steel and 4" A/C rough barrel, order x 3-12 JULY 01, 2017 REVISED: 08/07/2017. 1-800-426-9341 COUPLINGS . RC501 . PARTS LIST. APPROX.
