Does a filter system from Steinbach fit a pool from Bestway?
Not documented. Between the connections of Bestway pools and Steinbach filter systems our sources show no verifiable path — neither an adapter nor a documented interchangeability. That does not mean it cannot be done. It means we cannot document it and therefore recommend nothing.
What this is about
This concerns 95 recorded Bestway pools and 34 Steinbach devices: 30 Sand filter systems, 3 Filter ball pumps, 1 Cartridge filter pumps.
The connections
Every manufacturer has its own connection types. The same nominal size does not mean the same connection — the number describes the width, not the coupling.
- Bestway Ø 32 mm → Steinbach Ø 32 mm no part documented
- Bestway Ø 32 mm → Steinbach Ø 38 mm no part documented
- Bestway Ø 32 mm → Steinbach Ø 50 mm no part documented
- Bestway Ø 38 mm → Steinbach Ø 32 mm no part documented
- Bestway Ø 38 mm → Steinbach Ø 38 mm no part documented
- Bestway Ø 38 mm → Steinbach Ø 50 mm no part documented
- Bestway Hydrium surface skimmer (suction side) → Steinbach Ø 32 mm no part documented
- Bestway Hydrium surface skimmer (suction side) → Steinbach Ø 38 mm no part documented
- Bestway Hydrium surface skimmer (suction side) → Steinbach Ø 50 mm no part documented
What would settle the question
- An adapter whose manufacturer names both connections — then the path would be documented and would appear in the results of every pool concerned.
- A manufacturer statement that two connection types are interchangeable. Our register currently holds not a single one.
- Thread and diameter measurements of both sides from a primary source. Then the question could be calculated rather than looked up — and the result would probably be a documented exclusion, not a free pass: where two threads are recorded today, they differ at the same nominal size. The check does not yet know the thread and therefore stays at “unknown”; with two derived values that restraint is appropriate.
What is documented
Within one manufacturer things look different. Which devices fit a particular pool is stated on the page of that pool: all recorded Bestway pools .
