Pentair No. 175 Ball Bearing Polyurethane Wheel | ProVac & Super ProVac Flexible Vacuum | R201557Z

The Pentair No. 175 Ball Bearing Polyurethane Wheel (R201557Z) is the OEM replacement wheel for the Pentair ProVac and Super ProVac series flexible pool vacuums.

This wheel provides the rolling mobility the ProVac vacuum depends on to track smoothly across pool surfaces during manual vacuuming. The ball bearing construction reduces rotational friction for consistent, low-effort movement, while the polyurethane tread is formulated to resist pool chemicals and surface abrasion over repeated use. When a wheel becomes cracked, seized, or worn flat, rolling resistance increases and maneuverability suffers — this is the direct OEM replacement to restore proper function.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

The ProVac's wheel positions are numbered — confirm you are replacing the correct wheel position for your model by checking the exploded diagram in your vacuum's manual. If your vacuum pulls to one side or feels heavy to push, inspect all wheels for seized bearings before ordering just one; a second wheel on the same side may show similar wear. Replacing wheels in pairs maintains even rolling balance across the vacuum head.
