• Genuine Red Sea part 42208G2 — factory-correct fit for the REEFER 170 G2 overflow.
• Direct-fit replacement — seats exactly where the original downpipe sat, no modification needed.
• Restores the quiet overflow — a cracked or warped downpipe is one of the most common causes of a Reefer that's suddenly gone loud.

This part is specific to the REEFER 170 G2. The original (non-G2) REEFER 170 uses a different overflow downpipe, part 42208 — the two are not interchangeable. Check your cabinet or purchase documentation for the "G2" designation before ordering, or contact us with a photo of the overflow box.

• Suitable for: REEFER 170 G2 owners replacing a cracked, warped or noisy overflow downpipe.
• Not suitable for: the original REEFER 170 (G1), or any other REEFER size or generation.

Covered against manufacturing defects in addition to your rights under Australian Consumer Law. Standard freight — a compact plumbing part with no special handling requirements.

How do I tell my Reefer 170 is the G2?

Red Sea markets the REEFER 170 and REEFER 170 G2 as separate generations, each with its own overflow and plumbing parts. Check your original purchase details, or send us a photo of the overflow box and we'll confirm which generation you have before you order.

What causes a Reefer overflow to go noisy?

Most often a downpipe that's cracked, warped, partly blocked, or not fully seated, which lets air into the siphon. A genuine replacement restores the original clearances the silent-overflow design depends on.

Does this include the outer downpipe too?

No — this listing is the overflow downpipe only. The outer downpipe is a separate genuine part; check our other Reefer 170 G2 spares if you need both.

Is fitting straightforward?

Yes — it's a direct swap, no cutting or solvent welding required. Drain the overflow box before removing the old pipe.
