Product details
The Waterway 550-1831 is a PVC flex hose assembly, the piece that carries water from the pump to a sand filter. It is supplied made up, with a union fitting at each end.
The two ends are different
One end is a 2" union. The other is a sweep 90 degree elbow carrying a 1-1/2" union nut, which is what lets the hose turn into the filter without a separate elbow. The measured thread figures are given as about 3-1/16" on the 2" union nut and about 2-9/16" on the 1-1/2" union nut, which is the practical way to check it against your own equipment. The actual length of the assembly is 38".
Check the filter size before you order
The source names this hose two different ways. The product name and the detailed description call it the assembly for 26" sand filters, while the page metadata and the image caption call it 22". Both readings are on record, so take a tape to your filter and to the union threads rather than going on the title alone.
