Pentair Rainbow Vacuum Head Hose Swivel Adapter 258 | R201566
The Pentair R201566 is a replacement hose swivel adapter (often referenced as adapter 258) used on select Pentair/Rainbow ProVac and Super ProVac vacuum heads. This swivel connection helps the vacuum hose rotate more freely to reduce kinking and tangling while you vacuum, and it can also help prevent small suction leaks caused by a worn or cracked hose connection.
Key Features
- Swivel-style hose connection helps reduce hose twist and tangles during manual vacuuming.
- Direct replacement adapter for compatible Rainbow/Pentair vacuum heads.
- Improves suction integrity when replacing an adapter that is cracked, loose, or leaking air.
- Quick install (remove old adapter and press/fit the replacement into place as designed for the head).
Compatibility
- Rainbow ProVac flexible vacuum heads: 214R, 214, 222, 222R, 229
- Rainbow Super ProVac: model 241
- Rainbow swivel wheel flexible vacuums: 250 and 252

When to Replace

- The swivel binds up or no longer rotates smoothly, causing frequent hose tangles
- The vacuum hose repeatedly pops off the head during use
Installation Notes
- Turn off the pump before servicing any suction-side equipment.
- Remove the vacuum hose from the head and pull out the worn adapter (inspect the vacuum head socket for damage).
- Press/fit the new R201566 adapter into the vacuum head connection until it seats properly.

Maintenance Tips
- Rinse the vacuum head connection after use to flush out grit that can make the swivel bind.
- Store the vacuum hose straight (not tightly coiled) to reduce twisting that stresses the swivel connection.
- If suction feels weak while vacuuming, check the hose cuffs and swivel adapter for cracks or air leaks.
