Red Sea Reefer Sump Pump Return Outlet Nozzle Assembly
The adjustable factory nozzle that aims sump return flow into the display. This is the genuine Red Sea sump pump return outlet nozzle assembly, part number R42188, for the smaller-format REEFER range. It replaces a cracked, lost or seized return nozzle with the same adjustable factory fitting Red Sea ships new, so you can re-aim circulation exactly the way the system was designed to run.
Key features
- Genuine Red Sea part — the factory return nozzle, not a generic aftermarket fitting, so it seats correctly in the original plumbing.
- Adjustable direction — swivels to aim return flow across the display, letting you dial in surface agitation and circulation pattern.
- Drop-in replacement — fixes a cracked, brittle or missing nozzle without needing to source or fabricate a substitute fitting.

Will it fit my tank?
This nozzle fits the smaller-format REEFER range: Nano, 170, 170A, 250, 250 V3, 250 V3A, 250 G2, XL 200, 350, 350 V3, XL 425, XL 525 and 450. It is not the nozzle used on the large-format REEFER G2 625, 750, 900, S-850 and S-1000 range, or on the REEFER MAX — those run the ReefRun G2 DC return system with a different outlet fitting. Check your model name against the list above before ordering; if you're not sure which generation your tank is, the model name is printed on the cabinet plate.
Suitable for, and not suitable for
Suitable for replacing a damaged or missing return nozzle on any of the smaller-format REEFER models listed above. Not suitable for the large-format G2 625–S-1000 range or REEFER MAX, which use a different return fitting entirely.
Warranty and delivery
Covered by Red Sea's manufacturer warranty against manufacturing defects, in addition to your consumer guarantee rights under Australian Consumer Law. Ships as a small parcel item at standard freight rates.
Common questions
Will this fit my REEFER 750 or 900?
No. This nozzle fits the smaller-format REEFER range up to XL 525 and 450. The 625, 750, 900, S-850 and S-1000 use the ReefRun G2 DC return system with a different outlet fitting.
Can I adjust the direction of flow with this nozzle?
Yes — it's a swivelling assembly, so you can re-aim the return to shape surface agitation and in-tank circulation.
Is this a genuine Red Sea part?
Yes — Red Sea part R42188, the same nozzle assembly fitted at the factory.
My nozzle is discoloured but not cracked — should I replace it?
Not necessarily. Discolouration alone doesn't affect function; replace it if it's cracked, brittle, no longer swivels, or is missing.
