Aquarium intake strainer 12 mm - filter intake guard, 2 mm slots

Aquarium intake strainer 12 mm - filter intake guard, 2 mm slots

What it is

An intake strainer for aquarium filters: push it onto an intake pipe with 12 mm outside diameter (socket 12.4 mm, 20 mm deep, with a stop). 20 vertical slots of 2 mm keep fish, snails and plants out of the filter - for shrimp tanks take the 1 mm version or a pre-filter sponge. Measure your pipe first.

Free sample

This model is free - an honest sample of the series, so you can check fit, hole size and print settings on your own printer before you buy. The family has 8 models, it is also available as a discounted set, and the complete set holds all 60 sieves of the series (colanders, stackable sieve inserts, sink and drain strainers, paint strainers, fan dust filters, aquarium intake strainers and XXL sieves).

What goes with it

optional: pre-filter sponge for shrimp tanks

Which filament - food contact, heat, chemicals

Plain PETG (no glitter, metal, wood or glow filler) is widely used in aquariums; PP works too. No print is certified aquarium-safe - rinse well before use, at your own risk.

A stainless steel nozzle avoids lead from brass.

PLA slowly softens in warm water - not for a permanent tank part.
