Sealand 385318162 VacuFlush Ball, Shaft & Cartridge Kit

Sealand 385318162 VacuFlush Flush Ball, Shaft & Cartridge Kit

If your foot-pedal toilet has started running non-stop, refusing to hold water, or the pedal no longer springs back the way it used to, the internal ball and shaft assembly has likely worn out. This happens naturally over time, since the flush ball and its seal absorb wear with every press of the pedal. The Sealand 385318162 kit replaces that worn assembly with a fresh flush ball, a heavy-duty brass shaft, and a new spring cartridge, bringing back smooth, reliable flush action.

This kit fits a wide range of Sealand foot-pedal-operated toilets, including VacuFlush models and Sealand gravity-discharge units built with a metal lever inside the foot pedal. The brass shaft is engineered for long-term, heavy-duty use, holding up well under frequent daily flushing on an active boat or RV. Many owners plan on replacing this kit every four to eight years as routine maintenance, addressing wear before it turns into leaking, odor, or a stuck pedal.

While the toilet is opened up, it's worth pairing this kit with a matching Teflon and rubber seal replacement, since both parts wear together and swapping them out at the same time helps avoid a repeat repair later. Double-check your toilet model before ordering, since EcoVac heads with an all-plastic pedal and black spring cartridge require a different kit.

Frequently Asked Questions

Q: How often should this flush ball and shaft kit be replaced?
A: Most manufacturers recommend replacing it every 4 to 8 years, depending on how frequently the toilet is used.

Q: Will this kit fit an EcoVac toilet head?
A: No. EcoVac heads use an all-plastic pedal with a black spring cartridge and require a different replacement kit.

Q: What are the signs that this kit needs to be replaced?
A: Common signs include the pedal not returning to its closed position, water leaking or running continuously, or the toilet failing to fill with water properly.

Q: Should any other parts be replaced at the same time as this kit?
A: Yes, it's generally recommended to replace the Teflon and rubber seal kit at the same time, since both components wear at a similar rate.

Q: What type of toilets use this specific part number?
A: It fits foot-pedal-operated Sealand, Traveler, and VacuFlush toilets that use a metal flush rod covered by a plastic pedal cover.
