Spa, Jacuzzi & Hot Tub Parts and Accessories

Keep your spa, Jacuzzi, or hot tub operating at full performance with spa replacement parts and accessories from Waterway Plastics, Hydro Air/Balboa Water Group, and Tecmark. PST Pool Supplies stocks the jet bodies, suction fittings, wall fittings, eyeball assemblies, and spa hardware that most frequently need service or replacement, starting from $9.70.

Spa jets and fittings are the most commonly serviced components in any hot tub or in-ground spa. Waterway Poly Storm jet bodies are the threaded jet body housing that installs in the spa shell wall — the jet insert (nozzle) threads into the jet body, and the body is held in the wall with a flat gasket and retaining nut. The Poly Storm is one of the most widely used jet body systems in residential spas and in-ground pool spas. The Waterway Adjustable Cluster Storm Jet provides a multi-stream directional jet pattern with an adjustable face ring that lets the bather customize the spray direction and intensity. The Waterway SPC-2VP Hi-Flo Suction Assembly (1-1/2" hex, gray) is a portable spa suction fitting that provides the suction inlet for the spa pump — a component that often becomes brittle and cracks with age in portable hot tubs. The Hydro Air/Balboa Water Group Hydro Jet Gunite Wall Fitting is an inlet/return fitting for in-ground gunite spa walls — direct installation with a smooth white finish. The Waterway Eyeball Fitting Assembly (3/4" eyeball, 1-1/2" male pipe thread) is a directional return fitting for spa walls, allowing the return flow to be aimed at specific areas. The Tecmark TDI-3428 low-profile decorative button (black) is a replacement touchpad button for Tecmark spa control systems — used when the button cap deteriorates or discolors.

Spa jet bodies fail in two primary ways: cracking (usually from UV exposure on outdoor spas or physical impact) and stripped threads (from overtightening jet inserts or cross-threading during insert replacement). A cracked jet body allows spa water to leak behind the shell wall, causing structural damage over time — replace cracked jet bodies promptly. When replacing a jet body, always verify the thread pattern and outer diameter match the existing installation — Waterway uses a proprietary thread pattern that differs from Pentair, Jacuzzi, and other jet manufacturers. Jet inserts (the decorative nozzle face visible from inside the spa) are replaceable independently of the jet body and can be swapped to change jet pattern without removing the body from the shell.
