Attwood Marine Aerator Pump Nut Ring, For T800 800 GPH Pumps

Overview

The Attwood Marine 914040 is a replacement aerator nut ring for Attwood T800 800 GPH aerator pumps. It is a small service part, but it matters when you need to keep an existing livewell or baitwell pump setup working without changing the full pump assembly.

For boats that already use the T800 aerator pump, this part is a like-for-like repair item rather than a universal substitute. It fits the kind of routine service work that comes up when the original ring is worn, cracked, or missing and you want the pump assembly back together with the correct replacement part.

Key features

• Replacement aerator nut ring for Attwood Marine part number 914040
• Fits Attwood T800 800 GPH aerator pumps
• Useful for livewell and baitwell pump service when the original ring needs replacement
• Direct replacement format helps maintain the existing pump setup without moving to an improvised part

Compatibility and fit

This is a pump service part, not a general hardware nut or washer. The main check before ordering is the pump model already installed on the boat. When the system uses an Attwood T800 aerator pump, this is the matching nut ring for that application.

That makes it a practical match for owners, riggers, and service shops maintaining an existing baitwell or livewell system on a fishing boat. For other pump models, fit should be checked against the installed unit before ordering.

Installation and service

Replacement is typically handled during pump service, cartridge work, or when the assembly has been taken apart for inspection. Before reassembly, it is worth checking the mating surfaces and surrounding pump components so the new ring is not being installed over damaged or misaligned parts.

On boats that see regular washdown, vibration, and repeated use of the livewell system, small replacement pieces like this can save time compared with replacing a complete pump for a minor hardware issue.
