Product details
This is a single Kreepy Krauly hose section, part K21220, 40 in. long with a male end at one end and a female end at the other. It is supplied individually.
Replace sections, not the whole set
A cleaner hose is built from lengths that screw into each other, which means damage is almost always local. One or two sections crack, split or lose their ends while the rest of the run is fine. Buying single sections lets you fix exactly that, and it is also how you add or remove length when the cleaner is not reaching the far wall or is doubling back on itself.
Why a leaking section matters
Suction cleaners work on vacuum. A pinhole or a split anywhere in the run lets air in, and the cleaner slows down, loses its grip on walls, or stalls in a corner. Running a hand along each length with the pump on is usually enough to find the offender.
About the color
These hoses are commonly called blue. The actual color is closer to aqua, and there can be some variation between production runs, so a new section may not be an exact match to hoses that have been in the sun for several seasons.
