Dometic SeaLand VacuFlush Pump Bellows Kit – 385230980
The Dometic SeaLand 385230980 pump bellows kit is a replacement bellows assembly for VacuFlush marine sanitation vacuum and discharge pumps. The bellows creates the pumping action that moves waste through the system, so a fresh one brings back strong vacuum and dependable flushing.

Use it where your pump's parts diagram lists bellows assembly 385230980.
Fitment Notice
O-rings are sold separately. Confirm your pump model and cover style before ordering seals. Pumps with the 8-bolt cover commonly use O-ring kit 385310151. Stainless band-clamp versions use a different sealing kit.
When to Replace
Replace the bellows if it is cracked, split, leaking or distorted, or if the pump no longer holds proper vacuum or pumping action. Check the bellows any time the pump is opened for major sanitation service.
Installation Notes
Follow the Dometic pump service procedure. While the pump is apart, inspect the O-rings, bellows clamp, eccentric mechanism and duckbill valves.
Technical FAQ
Is this a sterndrive bellows?
No. The 385230980 is for VacuFlush sanitation pumps, not sterndrive drives.
My old bellows is marked 340671. Is this the right replacement?
Yes. 385230980 replaces the older 340671.
Are O-rings included?
No. O-rings are serviced separately. Match the seal kit to your pump's cover style.
Parts Desk Insights
Best use case: Restoring vacuum and pumping action on a VacuFlush S-, J- or T-series pump that has a cracked or leaking bellows.
Most common customer mistake: Confusing this with a sterndrive bellows, or reusing old seals. If you are opening the pump, inspect the O-rings and duckbill valves at the same time so you don't have to take it apart again.
Sizing and fitment guidance: Confirm that your pump's parts diagram calls for 385230980, and check whether your pump uses an 8-bolt cover or a band clamp before you order seals.
