SKU SIH-4
The SIH-4 snaps into a hole in the side of a sump of sewage basin allowing water or wastewater to enter the basin. It will set into the basin wall into the groove in the hub. The SIH-4 provides a water and vapor tight seal without caulking. Soap or other non-toxic lubricant may be used to allow the pipe to slide into the hub without difficulty. The SIH-4 will expand providing a tight seal.
