ProStar® replacement parts
Fittings and ProStar® parts
Return fittings, sweeps, wall steps, hydrostats and more, plus ProStar® replacement parts, ordered through your distributor.
The small parts around the shell
AquaStar lists return fittings, sweeps, wall steps, hydrostats, junction boxes, waterstops, winterizing caps, unions, plugs, rope anchors, Venturi-T fittings and umbrella sleeves, and its catalog says there are more. Most of them are small, and a pool cannot be built, opened for the season or closed for winter without them.
In general, a return fitting is where filtered water comes back into the pool, a hydrostat is a relief valve for groundwater pressure under the shell, and a waterstop seals the path along a pipe where it passes through concrete. Those are general plumbing roles, not AquaStar specifications. The catalog entry for each part carries its actual dimensions.

ProStar parts and the right part number
ProStar® is the name on AquaStar's replacement parts. The ProStar® leaf catcher, model HWN162, carries the same name and sits upstream of the CyberStar® cleaner. Like everything else AquaStar makes, parts are ordered through a local authorized distributor.
When a part number is in doubt, the Ventura office can confirm it. Mary Kaul's Google review describes a filter core assembly that arrived sized for a PLF 27000 when her filter was a PLF 35000. After she called AquaStar, her review says, "She gave me helpful advice and provided the correct part number."
The habit behind that story is a general one: read the model off the tank or the unit before you order, and have it in front of you when you call. The office is open Monday to Friday, 7:30 AM to 4:30 PM, on (877) 768-2717.
Catalog pages that open from a QR code
The 2026 Buyer's Guide Digital Catalog carries QR codes that open specs, install guides and support documents. For a fitting or a ProStar® part, that is a way to check a size or an installation detail before the order goes to a distributor.
AquaStar publishes no prices. They come from the distributor, who also has the stock and the lead time.

Fittings, grouped by where they sit
The catalog lists more than these, so ask the office if the part you need is not named. Skimmer lids and valves have their own pages: Skimmers and Fill-Lids and FlowStar® valves and flow meters.
