Genuine Spare Parts for the SunSun HW-702/703/704 Canister Series
The SunSun HW-700 series is one of the most common canister filters in Singapore tanks, and like any continuously running unit it needs the occasional part. This listing covers the wear items that actually fail first: the lid O-ring, the locking clips, the UV quartz sleeve on the B variants, and the impeller-with-shaft assembly. Keeping a fresh O-ring on hand saves you from a slow drip under the cabinet, which in our humid climate quickly turns into mould and a warped stand base if left unnoticed.
A canister that suddenly runs noisy or loses flow is almost always telling you the impeller is worn, chipped or fouled rather than the motor being dead. Replacing the impeller and shaft restores the original pump rating without buying a whole new filter. Smear a little silicone-safe lubricant on a new O-ring, seat it cleanly, and your seal holds. Match the exact part to your model from the selector, since the 702, 703 and 704 use different sizes despite looking similar.
Browse the full filtration equipment range for media and replacements. Our canister filter guide and pump noise reduction guide both help diagnose whether it’s the impeller or a seating issue.
