Dometic RV Toilet Flush Ball & Shaft Repair Kit - Brass Shaft with Teflon Ball, Fits Sealand/Dometic Foot-Flush Models (385318162)

Dometic 385318162 is a genuine OEM RV/marine toilet ball-and-shaft repair kit that replaces worn flush components to restore a tight seal and reliable foot-flush operation.

This compact replacement kit contains the core moving parts—Teflon ball, brass shaft, spring cartridge and mounting screws—designed for Sealand and many Dometic foot-flush toilets (except EcoVac and 5000 series; 5006 is compatible). It gives you the exact-type components used by the manufacturer so maintenance is straightforward, minimizes leaks, and extends the service life of older toilet assemblies when installed per the maker’s guidelines.

How will this kit fix a leaking or sluggish foot-flush toilet?

Worn ball seals or a corroded shaft are common causes of a toilet that won’t seal or that drips after flushing. Replacing the Teflon ball and shaft restores the original sealing surface and movement, while the spring cartridge returns proper tension to the valve action.

• Replaces worn Teflon ball to re-establish a watertight seal
• New brass shaft reduces play and resists corrosion
• Spring cartridge renews valve tension for responsive flushing
• Includes screws for a complete, one-stop repair

Which Dometic/Sealand toilets is the 385318162 kit compatible with?

The kit fits most foot-flush Sealand and Dometic marine/RV toilets but explicitly excludes EcoVac and the 5000 series models; the 5006 model is supported. Always check the toilet model number and manufacturer fit notes before ordering to ensure correct compatibility.

• Compatible: many Sealand and Dometic foot-flush toilets including model 5006
• Not compatible: EcoVac line and 5000 series toilets
• Verify your toilet model number on the unit or owner manual

What’s included and what tools or skills do I need to install it?

This kit ships with the Teflon ball, a brass rotor shaft, a spring cartridge, and the mounting screws required for installation. Basic hand tools and intermediate DIY skills are usually sufficient; if you’re not comfortable disassembling toilet hardware, a professional or marine service tech can complete the swap quickly.

• Time: often 30–60 minutes for experienced DIYers

How long should I expect these replacement parts to last?

Longevity depends on usage, water quality, and maintenance frequency; using OEM-quality materials like the Teflon ball and brass shaft helps maximize service life. Regular inspections and prompt replacement at the first sign of wear will prevent more extensive repairs and keep the toilet functioning reliably.

• OEM parts typically outlast aftermarket alternatives under normal use
• Inspect seals and moving parts seasonally in marine or RV applications
• Replace at the first sign of leakage, sticking, or poor sealing
• Proper installation and periodic cleaning extend component lifespan
