Clip the hose on and walk away. Replaces your existing filler cap.
- Click your hose straight on — no holding it in the hole
- Vented — air escapes as the tank fills, so it doesn't burp back at you
- UV-stable — built to live outside, not go brittle in the sun
- Standard brass click-on fitting, works with any garden hose
- Swaps out your existing cap. No drilling, no plumbing
- Suits genuine Seaflo and Seaflo-pattern filler necks
Filling the tank shouldn't take two hands and ten minutes.
This replaces the filler cap already on your van with one that has a click-on hose fitting built in. Clip the hose on, turn the tap on, go do something else.
There's a breather vent in the cap, so air gets out as the water goes in. No airlock, no blowback, no standing there waiting for it to settle.
It's made from UV-stable material, so it lives on the van permanently and stays on it. No adaptor rolling around in a drawer for when you need it.
Which one have you got?
Check your current filler cap before you order.
- Alko / Hume screw-on — threaded, twists off
- 3-Tab locking — three tabs, quarter turn

FAQ
Will it fit a knockoff Seaflo filler?
Yes. Most copies use the same pattern. If you're not sure, send us a photo of your filler neck and we'll tell you before you order.
Will it go brittle in the sun?
No. It's made from UV-stable material — it's meant to live on the outside of the van.
Do I need a special hose fitting?
No. It takes a standard click-on fitting, the same one already on your hose.
Does the cap stay on while I'm driving?
Yes. It replaces your existing cap and locks the same way.
What if I've got a different filler neck?
Send us a photo and we'll tell you straight whether it fits.
