Genuine Dometic Water Supply Hose Kit for 300/310/320 Series Gravity-Flush Toilets
Restore a tight, leak-free water connection to your Dometic 300, 310, or 320 series pedal-flush toilet with this genuine OEM supply hose kit.

This kit includes the nozzle, gasket, and hose needed for a complete, hassle-free replacement — no need to source individual components separately.

How to Confirm This Is the Right Hose for You
This kit is designed specifically for Dometic's 300, 310, and 320 series pedal-flush (gravity) toilets, connecting your fresh-water supply line to the toilet's water valve. Note that this differs from the toilet's fresh-water inlet connector, which can vary by model (some use NPT threaded fittings, others use different connector styles) — if you're troubleshooting a leak specifically at the wall/supply-line connection rather than at the toilet's bowl supply hose itself, check your owner's manual or contact us to confirm you need this part versus a different supply-line fitting.
Frequently Asked Questions
What's the difference between this and a water valve kit?
This is the supply hose that runs from your water valve to the toilet bowl — it delivers water into the bowl during flush. A separate water valve kit (which regulates water flow from your fresh-water line) is a different component; if your toilet won't add water at all (rather than leaking from the hose), you may need the water valve instead.
My toilet is leaking at the base — is this the right part?
If the leak is coming from a cracked or brittle hose connecting your water valve to the bowl, yes, this kit will fix it. If the leak is from the bowl-to-floor seal instead, you'll want a base seal/gasket kit, not this supply hose.
Does this include the hose clamps?
This kit includes the nozzle, gasket, and hose. If your existing hose clamps are also worn or damaged, we recommend having new clamps on hand for the reinstall.
Will this fit my Dometic 301 or 321 series toilet?
This kit is specified for 300/310/320 series. The 301 and 321 series may use different or additional components — check your model number or contact us to confirm fitment before ordering.
