Structural Dome Hole Funnel

The Pentair Structural Dome Hole Funnel is a purpose-built installation tool that makes loading media into bayonet-style dome-hole mineral tanks fast and mess-free. Structural composite tanks with a dome-hole top use a distinctive bayonet fitting, and this funnel is shaped to seat into that opening so you can pour resin, gravel, carbon, or other media straight into the tank without spillage or fuss.

Filling a treatment tank by hand is awkward and wasteful, with media spilling around the opening, slowing the job, and creating a cleanup chore afterward. A properly fitted funnel directs the flow cleanly through the dome hole, speeding the process and ensuring more of your media ends up inside the tank where it belongs. That efficiency matters whether you are building a single softener at a customer's home or loading a batch of filtration tanks in the shop.

• Designed for bayonet-style dome-hole tanks
• Funnels resin, gravel, carbon, and other media cleanly
• Reduces spillage and speeds tank loading
• Fits Structural composite dome-hole openings
• Reusable installation tool
• Lightweight at approximately 0.55 lbs

Because it is matched to the Structural dome-hole geometry, the funnel seats securely during pouring rather than slipping or tipping the way a generic funnel might, which keeps both hands free to manage the media bag. That stability is a real advantage when pouring heavier media like gravel underbedding or when loading several tanks in sequence. The funnel is reusable build after build, so it quickly pays for itself in saved time and reduced media waste across a busy installation schedule. For installers and service technicians who regularly assemble Structural composite tanks, the Pentair dome hole funnel is an inexpensive, practical tool that brings order and speed to one of the messier steps of building a softener or filter. Keep one in the install kit and tank loading becomes a clean, quick task every time.

Stored with the rest of the install kit, the funnel is ready whenever the next Structural tank needs filling, and its simple, durable design means it will serve through countless builds. For any professional who works with dome-hole composite tanks regularly, it is one of those small tools that quietly makes every job go faster and cleaner. Inexpensive and endlessly reusable, it is a practical addition to every installer's toolkit.
