This replacement body seal is for owners of SunSun HW-704A and HW-704B external filters whose original O-ring has worn out or started to leak. The seal sits at the filter body joint, so its condition directly determines whether the unit runs without leaks.
Why it matters
- Original SunSun part: it is sold for the HW-704A and HW-704B models, so the fit matches the factory specification.
- Leak prevention: a intact seal at the body joint keeps water inside the filter during operation.
- Simple replacement: the item is a single O-ring, so the worn seal can be swapped without replacing the whole filter.
- Stable system operation: a sealed filter body helps the filter keep running reliably as part of the aquarium setup.

It is a body O-ring that keeps the filter housing sealed, which helps prevent leaks when the old seal wears out.
The price is 17.99 PLN gross (including VAT).
The listing covers only the HW-704A and HW-704B, so I can't confirm compatibility with other models. Please check your filter's model before buying.
