Sealand 385311226 Bellows Clamp Kit for S/T-Series Pumps
Keeping a marine sanitation system running smoothly often comes down to small parts doing a big job, and the bellows clamp is a perfect example. The Sealand 385311226 bellows clamp kit is built to hold the bellows assembly firmly in place on S-Series vacuum pumps and T-Series discharge pumps, preventing the slips and leaks that can turn a minor maintenance task into a much bigger headache. Each kit includes two clamps, giving you exactly what you need to complete a proper bellows installation in one go.
This kit is a practical choice for boat owners and technicians who are already replacing a bellows assembly or performing routine upkeep on their Vacuflush toilet or waste pump system. Because it's designed to match the fit and function of the original equipment, installation is straightforward and the seal stays reliable once everything is tightened down. It also works across a range of compatible pump models, so it's worth keeping on hand as a spare for future service work.
Beyond fitting properly, the value of a clamp kit like this comes down to trust in the material and the seal it creates. A clamp that loosens or corrodes over time can lead to slow leaks that are hard to trace, so choosing a kit made to match Sealand and Dometic specifications helps avoid that kind of frustration. For anyone maintaining a marine vacuum or discharge pump, this small kit plays an outsized role in keeping the whole system watertight and dependable.
