Hagen replacement intake tube with basket for aquarium filters models 305/405, 306/406 (MPN 81527)

Hagen replacement intake tube with basket for aquarium filters models 305/405, 306/406 is a direct-fit intake assembly designed for external canister filters. The unit combines a rigid intake tube and a pre-filter basket that prevents large debris from entering the filter, helping to maintain consistent water flow and reducing the risk of impeller blockages. It is intended as a maintenance part for freshwater aquariums using compatible Hagen filter models.

Advantages

The replacement intake tube restores proper water intake by matching the original dimensions and connection points of compatible Hagen canister filters. The integrated pre-filter basket captures leaves, gravel and other coarse particles before they reach the impeller, which reduces mechanical wear and the need for frequent internal cleaning. Constructed from durable plastic, the assembly resists corrosion and is easy to remove and reinstall during routine service.

Suitable for

• Routine replacement of worn or damaged intake assemblies on compatible external canister filters
• Freshwater aquariums that require debris protection for the filter impeller
• Maintenance tasks where easy removal and cleaning of the intake basket is needed

Key specifications

• Material: durable, corrosion-resistant plastic
• Includes: rigid intake tube with snap-fit pre-filter basket
• Compatibility: designed to fit the specified external canister filter models that use this intake geometry
• Function: prevents large debris from entering the filter and protects the impeller
• Installation: tool-free attachment and removal for service and cleaning

How to use

Turn off and unplug the filter and associated electrical equipment before performing any maintenance. Detach the existing intake tube from the filter housing according to the manufacturer’s instructions. Install the replacement intake tube by aligning the connection points and snapping or twisting it into place until secure. Ensure the pre-filter basket faces the aquarium and is positioned to avoid contact with substrate or décor. After installation, prime the filter if required and restart the unit, checking for normal water flow and secure connections.

Usage recommendations

Inspect and clean the pre-filter basket regularly during water changes to remove accumulated debris. Avoid placing the basket directly on fine sand or loose substrate to prevent clogging; use a small lift or protective guard if necessary. Replace the intake assembly if cracks, excessive wear, or persistent flow reduction occur.
