Refer to Victaulic Pocket Handbook I-100 for special safety cautions when used for concrete pumping.

Style 78 Snap-Joint couplings are designed for quick disconnect service. Mated housing are hinged with an attached locking handle for assembly. Housings through 4" (100 mm) size have a smooth outer surface. Larger sizes have cross-ribbed design for added strength.

Style 775 couplings are designed specifically for use on radius cut grooved or standard roll grooved rigid plastic pipe. The housing is designing with "wing" extensions to increase joint strength by reducing stress concentration at the groove/key engagement and transferring it to the full wall of the pipe body.
